Great points.
My one issue with Hollywood Studios that would make adding Indiana Jones there challenging (although far from impossible) is that it would probably involve building a new, exotic environment far removed from Hollywood. Currently everything in Hollywood Studios is themed to Los Angeles, Emeryville, or just movie-maving and backlots in general. An Indiana Jones land would require building something not part of that environment, probably a jungle or desert-themed environment (unless they were to take a movie-making approach like the current stunt show).
I wouldn't object to that changing though; a Star Wars Land would probably shift that whole theme away from Hollywood anyway, so it's probably a moot point. At any rate, the lushness of a jungle area would probably do Hollywood Studios some good.
