You might be on to something. If they take out the section from the midcourse to the break run, and redesigned that to go more towards the lagoon and lighthouse, it opens quite a bit of room. I did a quick rough sketch moving it and making a fake new layout:
Take the green track out, put some kind of new layout where the purple is. That opens the yellow area(assuming the removal of storm force) for the Avengers ride or whatever. Thats about 80,000 SQ Ft marked off there. they could still preserve that turn around and the backstage buildings if necessary. If those buildings by doom aren't necessary, it opens up even more if they really wanted to go overboard.
Now does anyone know exactly which areas of track they are removing? I can't tell from the pictures.
