lol, Hamilton, Avenue Q, Rent or In The Heights aren't what I would consider "Theme park appropriate". Wicked is more the direction i'd expect them to go. Or Shrek: The Musical now that they own that (If you haven't seen it, don't judge - it's actually really good).
If they build a second CityWalk type area though, it wouldn't surprise me if they built a Broadway caliber theater that can host sit-down or touring productions.
