What could work from the list:
Bambi-If they don't put Pocahantis, then this might actually work as a mini-game world
The Sword In The Stone-Yes, this will give the past of Merlin! Maybe you'll encounter Yen Sid too
The Jungle Book-Possibly Yes
The Many Adventures Of Winnie The Pooh-The Hundred Acre Woods was in every game, so maybe it will show Pooh befriending Ven or Terra
The Little Mermaid-Yes to learn why Tritan hates the Keyblade
Beauty And The Beast-Maybe Beast has a cameo in another world like in KH 1
Aladdin-IT IS GOING TO BE IN BBS
The Lion King-This could work, showing how Simba came to be
Pocahontas-If Pride Lands or Bambi is not used, then totally
The Hunchback Of Notre Dame-It would be interesting, but not I can't picture having party members from this movie
Lilo And Stitch-Yes, this definitly can. But I would rather prefer it with 358/2 Days or KH 3 because it would be funny if Sora turned into an experiment, or Roxas
An Extremely Goofy Movie-Lol, learn about Goofy before he was a knight
Finding Nemo-If Little Mermaid isn't in it
A Goofy Movie-See above
The Incredibles-Yeah, that could work, and in the beginning you get to choose the party member
The Nightmare Before Christmas-It's tradition by now
Toy Story-Yes, but not BBS, but KH 3 because Sora would be funny as a Robot, Donald an Airplane, and Goofy a Jack-in-the-Box
