I do have one question though. Donald was the one responsible for 'keeping the world order' and all that and giving the crew their disguises. In this case, Morgan is pretty much taking over the Donald role since she's not a Keyblade wielder but a mage, so question is- Where are they getting their disguises from? Morgan doesn't know what that order is to begin with and even if she did probably wouldn't care, nor have the magic required to disguise the group.
One idea is when the group meets Merlin, he hears they are going to other worlds and gives them something that will automatically disguise them when they enter a world.
That way we can say 'A Wizard did it'
That works but since some wielders won't be in Traverse Town or with Donald there could be a locked "World Survival" function that activates upon entering other worlds. At least with the ones whose keyblades wield or attuned for strong magic.
