I just don't see a ride where the premise is "join the cops on a police chase after going through a queue that's a prison" playing well to a modern American audience. Even ignoring how out of place that would be in the Magic Kingdom it just isn't gonna work
Moana feels more like Adventureland but there might not really be room there. Plus, the only actual "Polynesian" part of Adventureland at wdw is the Tiki Room. Perhaps the Tiki Room could get moved (along with a slight update) to the new Moana/Polynesian area which would help that land (or mini-land whatever) feel less like just a single IP. Take out the theater and Magic Carpets. Fix that horrible bottle neck. And add a new A-Ticket or meet and greet in that space that will take up less room
Villains works. I like that the best since it isn't a single IP, just based around a vibe or a concept which feels very fitting for Magic Kingdom since most of the other lands are more vibe/concept based rather than immersive areas or IP based. A Haunted Forest or spooky carnival or ruined castle or whatever full of Villains that uses Haunted Mansion as a transition point to Liberty Squarr sounds like a slam dunk as long as they don't get too intense that it scares little ones away
I don't put much stock in what he says as being reliable, but aside from Zootopia I could see this working well.
