What if they named Disney-MGM to Walt Disney Studios Florida? It's fairly unlikely, but it's possible... I think, in respect of the original theme and its history, they should name it "Disney's Hollywoodland" or something. It should have Hollywood in the title.
For Paris, I like that ours is Walt Disney Studios made up of several different studio areas - Hollywood, Toon, Backlot. It's like the lands of DL but movie genres/themes instead of storybooks.
Disney-Pixar Studios would also confuse people because of Toon Studio.
