The thing about the physical changes that we saw with Sora, Ven and Vanitas was that neither of the two changed by it had yet been given a physical form/facial definition.
Ven affected Sora because Sora's heart had just been created and he didn't exactly have a body of his own yet (Nomura basically suggested in one interview that he had intended Sora's heart to have appeared to Ven before he was born, but he avoided that because Western countries think the metaphysical heart doesn't exist until birth [?!?]). Even assuming that Sora was an infant, though, he still had plenty of growing to do that could easily make him more Ven-like (and eye color isn't set until later on anyway).
Sora affected Vanitas because Vanitas was basically just an Unversed with a human shape. He didn't have a face under the helmet, so when one was created, it was influenced by Sora.
Ven wasn't affected because he was old enough for his features to have been completely defined.
Now, of course, in this theory all of the yellow-eyes-and-pointy-ears people are old enough that they should be more like Ven. The thing is, though, Ven was allowed to rest in Sora's heart with no interference at all on Sora's part. Regardless of how he did it, a connection to Xehanort would be bound to be more invasive and malignant -- Sora's heart shelters others, while Xehanort's heart confines and suffocates them.
Yeah.
I mean, one of the things I was thinking about was, for instance, would Sora technically look more like Kairi from hosting her heart? Well if we're going by the example set by Terranort, it's hard to say. Terra's skin, eyes, ears and hair changed to look more like MX's. But for Sora, most of this would not change even if Kairi's heart had an effect. White skin, blue eyes, round ears, not much difference between the two. The only notable difference is Kairi's red hair, and obviously Sora does not gain red hair lol.
So what gives? What's the difference? For starters, I think Xehanort is, as you said, more "invasive and malignant." Xehanort was taking over through the power of darkness, Kairi was seeking shelter through the power of light, so I really doubt her heart would have any physical effect on Sora.
But what about Ven's heart (assuming it did influence Sora's appearance)? That would have to do, I imagine, with the intimacy of the connection. Sora's connection to Ven is stronger than his connection was to Kairi. He's not just harboring Ven's heart, he's filling in the missing place, the two hearts are deeply merged, which I think is a reasonable enough explanation for the physical alterations.
So, going back to Xehanort, could he produce the physical changes in the seeds through simply "connecting" to their hearts as opposed to actually placing a piece of his heart in them? Because of the power of darkness, that really wouldn't surprise me. But as I've said, I still find it easier to account for these physical changes through a much more... concrete idea such as the horcrux theory.
Then Xehanort made a bad move though on keeping his seeds alive, lol, I thought these were made by him in case his possession of Terra fails...if they're "killed" (sent to sleep or whatever) wouldn't that contradict his plans?
All others except Vanitas of course, as having the dark "core" of the X-blade already ready at his hands is surely a boon for Xehanort's plans.
It depends, really, because I'm sure he'd be aware that there are multiple consequences to placing pieces of his heart in others. It's a matter of what his primary motive is in doing so.
Increased chances of survival is definitely one result, but it doesn't necessarily have to be his primary motive.
As we were talking about earlier, Braig's heart may have been "harvested" by Xehanort in that DDD scene, so obviously it would be silly for him to be essentially killing one of his seeds if he were just using them for survival.
Consuming the hearts of his seeds and creating an amalgamation of hearts could be a part of some further scheme of Xehanort's, though I'm not too sure what it could be. I mean, I'm sure that will make his darkness
much stronger (acquiring the darkness of Braig, Isa and Vanitas), but there's probably something more to it.
The one question I have though....when did MX get the time to put a piece of his heart within Isa. For all we know, at this point, he never interacted with them in BBS.
And if he did it as Apprentice Xehanort, that would be harder wouldn't it. Since he'd have to deal with Terra/Eraqus too...didn't the hearts within the body merge together?
It would have to be as Apprentice Xehanort, obviously.
I don't think it's that much of a stretch for him to be capable of doing it as AX.
I mean, look at when he split Ven's heart. He was able to, with precision, separate the dark half from the light half (and that's not even his own heart). The man knows what he's doing. Furthermore, he was capable of detecting the hearts residing within him, as we see in the secret ending. So all he would have to do would be, yes, to make sure to remove a fragment of his own heart and not Terra's or Eraqus', and I fully believe he'd be able to do that.

Re:Van-Sora looking alike
It still doesn't really make a lot of sense. If I dig a hole and then fill it with sand, the dirt around the hole and the sand may very well mingle, but the displaced dirt shouldn't have any connection to the sand I put in. Hearts are more complicated, of course, but that's where my brain hits a speedbump logic-wise lol. I think in reality it's just that Nomura thought an evil Sora would look cool, and Ven looking like Roxas would be a cool twist that would stump people in the secret trailer, and then he wrote around that idea. So I'm not sure if he will bother to keep using the logic he made up for Ven/Vani/Sora in other similar characters, if he has other cool ideas for them...
Yeah, good point, I mean, Nomura was actually considering making Ven look like Sora and Vanitas look like Roxas, so he definitely just wanted more look alikes and the logic behind it was an afterthought.
That's another reason why I don't want it to be caused by a heart-connection, because the reasoning just isn't as strong. It could still work buuut...
I think it's important to remember that Nomura was speaking from the perspective of a Japanese man to a Japanese audience, and unless you are Japanese too (idk if you are) he therefore probably has a different body of ideas and associations behind his use of the word 'death'.
For example, some of the concepts surrounding Kingdom Hearts itself is pretty eastern: a body of spirit energy from which every soul is born? Entire worlds having souls of their own from nature? The confusing distinctions and specifics of the concepts of heart, body, soul (aka the life force of the body, said by Nomura to animate the Nobodies), memories and persona in this series?
It reminds me of how I read that in Shinto belief, when people die, after a certain time at least part of their soul becomes part of a collective ancestor spirit. I'm not an Easterner myself, but from what I've read about Shintoism it seems to me that their ideas about the 'soul' and 'self' are very different.
So perhaps, when Nomura says there is no 'death', he means that there is no death in the sense that the characters' souls lose their individuality and merge into some sort of collective or amalgamation (like Kingdom Hearts is said to be. Perhaps having such a symbolic entity in the series already made him feel like he needed to stress the difference in that interview).
In which case, the concept isn't that different from the Western concept of the afterlife. To a typical Westerner, I'd say that we consider our souls to be the embodiment of our selves, and even after death that soul contains all the information that makes us 'us' as we are. Which sounds a lot like what Nomura meant by having the characters 'sleep' as they are.
This series has other concepts that sound Western, too. The consequences of the Keyblade War are so much like Original Sin, and I've seen some interesting connections between the X-blade and the Keys of Heaven.
The RoS reminds me of Sheol, though that state of existence is described more as a dreamless sleep.
I think it's pretty appropriate for death in KH to be referred to as "sleep," as it is in the Bible, because the word evokes the idea of an inevitable awakening, which, as we know, seems to be the direction the series is taking.
