I was thinking if you have played 1.5, 2.5, and 2.8, in KH3 after Sora gets his new clothes, the bonus you get is a pallet swap for Sora's new outfit that represent each of Sora's clothes: KH1 Sora, KH2 Sora, and KH3D Sora. Of course, to make this fair for the people who hasn't played them/didn't get a chance to, they can be achieved by doing some challenges within the game.
