Is Marluxia proof what other main villains would've been like besides (Ansem, Xehanort)

[5glitchers5]

Let's think about before all of the other games and their ideas were even thought of. The main villian in KH was Ansem, and now although Org. XIII has already been planned, them making a new main antagonist for that game was indeed clever. However I feel that that opportunity has never came back. It makes me wonder that if KH took a different route and each game/ each couple of games had it's own villain. What do you think it would've been like? Personally I say better and this is the route I think the series should've taken.

I don't think that's how'd it have been per say but Marluxia is likely an outline of what you would've gotten.
