Strictly speaking to the space currently held by the theater, you're correct. However, I took a look at Spider-Man's show building for reference (it's a lot bigger than I thought, actually); if the land developers and Creative so chose, you could place a show building in place of the theater that, edge-to-edge between Spider-Man and Comic Strip Cafe, would be about as big as Spider-Man's, if not a little smaller to account for breathing room.
