Like the idea.
Since you brought up moving rides to EPCOT and the park is "evolving" (losing its core identity), I would really like to see one of the new districts (or future expansion) be dedicated to "lost" Disney. Bring back a few historical rides/pavilions that were crowd favorites and try to develop a cohesive theme in some manner. My vote would be for Wonders of Life Pavilion, Horizons, 20,000 Leagues Under the Sea and Alien Encounter. World Celebration would have been a great name for this area. Oh well.
