It could work if some of the animation is more teen/adult-skewing
- SpongeBob
- Warcraft (the games are animated)
- Legend of Zelda
- Mario Bros/Donkey Kong/Yoshi's Island
- DreamWorks (similar layout as Fantasyland)
- Pokemon
- The Big Apple (stylized NYC with toon IPs like SLoP or TMNT)
- Laika/Roald Dahl (Coraline, ParaNorman, Boxtrolls, Kubo and the Two Strings, Willy Wonka, etc)
Hanna-Barbera would be much better as a Toon Lagoon replacement.
Scooby-Doo replaces TL theater, Jetsons takes over carnival games/Comic Strip Lane area, Popeye stays as is, Flintstones and/or Wacky Races replace Dudley
I like the toon-based concept. It leaves USF and IOA open to live-action IPs and gives the 3rd gate a thematic hook/cohesion.
