It's disappointing because I really like the idea of LC. But the seams started showing the moment they changed Poseidon's Fury to the Darkenon version. It showcased a... I guess a disconnect... between what the land could be and what it was.
A big part of me would prefer the Lost Continent theme remain, just give the land a massive overall. Including the removal of PF as a walk-through. For context of what can fit (and arguable, this would go for an entire redo of the land), Transformers can fit where Sindbad sits and Cat in the Hat fits where Poseidon sits, with enough room for a flat ride in front (Storm Force used for scale). This doesn't even touch the main path or the access road. The question becomes how do you re-theme Lost Continent with rides instead of shows, especially when DisneySea has a Sindbad ride already. And you do it by beating Disney at its own game.
For the Poseidon plot, you remain true to the location with a Greek myths, only this time you build a ride based on the Trials of Hercules. This is the more thrilling ride of the two, something akin to Spider-Man only with more practical sets. It's a public domain character, and Disney hasn't done anything with him in the parks. So Universal should use him.
In the Sindbad plot, the lower-key attraction sits. Fitting in with the Mediterranean market, we join Scheherazade as she tells us the stories from 1001 Arabian Nights. Another practical attraction, this would be a trackless ride similar to Mystic Manor. The Mystic Fountain gets a retheme to BE the queue entrance as an Oracle Fountain.
