Yes I would.
This is what I would like to happen (but I wont my breath):
Mickey's Scenerio as the last and shows the true ending. Anyone played BlazBlue? After you do everyone's story, the True Ending unlocks and you play through it. I would love it if, after you finish one Scenerio it ends in a cliffhanger, making you want to do the next character's Scenerio even more. And once all 3 Scenerios are completed, Mickey's Scenerio unlocks and you play as him to finish the game.
Why? Because everyone is so head over heels for these three chareacters and Mickey deserves a bigger spotlight after playing minor roles in previous games, despite him being Disney's biggest star. He deserves a (significant) part where you play as him and has plot consequences. I think the end would be perfectly badass, when he arrives to help the other three fight Xehanort and Vanitas. And hey, to add insult to injury, Terra, Ven and Aqua should be HIS support characters. lol
But alas, I know that will not happen, but I'd give major kudos to Nomura (a man i hate) if something similar like that happens.
