If they're tossing a lot of the 'studio' type theming that the place was originally designed for (ie: the tour, the backlot, etc), then the most obvious area for me to be overhauled would be the huge chunk of space right in the center of the park that is very little used/needed - American Idol, the Sounds Dangerous building, Commissary, and the space used for Character greets behind it. ; That would allow a big chunk of the expansion for Star Wars land without needing to use as much additional land, and really fill in the park space better as AI is a dying show and can't have too much more life left at DHS, the Sounds Dangerous building is closed half the year, and the commissary is superfluous given the other, better eating spaces in the park.
