You could make a finished game with different characters and different names, but with the ability to change both.
Then "someone" would release an asset pack substituting the names to the ones we would really like to see.
No one would of course know where said package came from if asked. ;-)
I don't see how any lawyers could object to that.
You'd still make money of of the game and you would probably make Disneys interest in the franchise null.
