Great point. I didn't even factor in Dreamfinder. They created a popular Original Epcot IP that is basically being left to rot (or in Dreamfinder's case, dead), yet the they have gold and just can't see it. The story line fit perfectly as well.
While Disney had a pretty bad history with turning other attractions into movies (Except for The Pirates of The Caribbean). The Figment comics by Kim Zub is the only Disney attraction that I think would be the perfect opportunity to bring Dreamfinder and Figment back to the limelight to not only WDW fans. But giving Journey Into Imagination more exposure to the general public. Even Tony Baxter approved of the Figment comics.
I seriously recommend buying a hardcover version of these two since it contains concept art of the original attraction and other stuff.
