I think an Inside Out ride would fit great over in the Imagination pavilion. But I really want Stitch to become something Incredibles!! (And I still want HS to become an entire Star Wars park......)
I think it would be cool if they turned a movie like Fantasia or Alice In Wonderland into either an interactive play area or a walk-through ride. Or even just had something like an 'enchanted trail' with characters incorporated (maybe not full meet and greets, but live characters waving from the sidelines.) I feel like the last time my nephew went, I was super excited to show him the animatronic rides but he didn't really get it, the idea of just sitting still and watching it go past. I realized he's from the "STEM / STEAM" (and video game / iPad) generation who's used to everything being hands on and interactive - since he could walk he's been at interactive science and children's museums and such, and used to seeing stunning animations in movie theaters. He definitively favored the interactive elements of the parks and the thrill rides. It would be cool to have a ride that incorporated some of those 'hands on' elements (maybe like the flowers from Fantasia that would light up, make music or move if you touched them,) with some 'ride' elements like slides, with a character or two. I noticed that in Disneyland Paris they do have some walk-through attractions, but I don't know if in Disney World the sheer volume of visitors and potential liability would make that untenable.
