Hmm, sounds like a fun idea.
Let's see, I'll go for two or so attractions from each park.
From Magic Kingdom, I'd pick:
- Splash Mountain
- Thunder Mountain
- Buzz Lightyear's Space Ranger Spin
- TTA
From Epcot:
- Spaceship Earth
- American Adventure
From MGM:
- Rock 'N Roller
- Muppets 3D
- Voyage of the Little Mermaid
- Who Wants to be a Millionaire Play It
From Animal Kingdom:
- Dinosaur
- Tarzan Rocks
- Festival of the Lion King
From
Disneyland:
- Indiana Jones Adventure
- Pirates
- Haunted Mansion
- Space Mountain
- How about all of Fantasyland?

If not, then the 5 "biggies": Pinocchio, Snow White, Peter Pan, Mr Toad, and Alice in Wonderland
Then, I'd have to throw in a couple from Islands of Adventure:
- Dueling Dragons
- Poseidon's Fury (or whatever that Atlantis attraction is!)
- Voyage of Sinbad
Then, I'd like to throw in the entire Mermaid Village thing from Tokyo Disney Seas
I think the park is getting fairly crowded now, so I'd better stop there.
