So I finally got this to work. The problem I had before was that I tried normal animation mods. But that made Mickey completely invulnerable. What I had to do was to animation mod movement/hurt animations the same way you would mod un-looping animations in "play as [boss]" codes.

Press and hold R2 while skipping the cutscene. Press L2 once when the battle starts. Mickey only has 4 attacks to work with, though, so I can't do much, even with Terra's many attacks to replace. Speaking of replacing attacks; I left the attack/magic lock attack untouched, because it freezes if you do anything with it. Another "side-effect", if you will, is that Mickey can be hit at certain times during the desperation move, which ends it instantly. I don't know if it will lead to freezing or not. Should you find some problem with the code (freezing, Mickey getting stuck in an animation, etc.) go right ahead and let me know, and I'll see if I can do anything. Not so easy to thoroughly test a code like this.
