I wouldn't mind one whit if they changed the whole thing to "Soarin over WDW." The Disneyland sequence at the end of the current film is my fave part right now, and it would just be a neat experience to fly over the entirety of WDW.
Think of the cool possibilities - you could smell SSE, and Rome burning as you fly over it, catch a whiff of pineapple as you soar over Adventureland, see a baseball being hit out of the park over at the sports complex.... it would be cheaper to produce than anything over the USA, and it would offer a different perspective of the parks. Sadly, this will only probably exist in my imagination...
