Not WDW but check out 'Disney: The Castle'. Only temporary, and certainly very constrained in what was there (following islamic conservative values), but an interesting indicator about whether such a MK park would work there. Then again, the repressive regime would go %100 against the Disney message about inclusion. Keep in mind the various protests when world sport organizations decided to hold events there. And those were one-shots, so to speak, as opposed to a park that would last for a very very long time.
