The Imagineering angle has been my thought, too, for awhile. A reincarnation of the original would fit well, as it could showcase some of the team's best effects in an attraction and IP created from the ground up by WDI. The ImageWorks concept lends itself perfectly to attraction or other design. You could showcase upcoming attractions in a display space. The theater could be tied to that. You could even, if necessary, do an Inside Out tie in, navigating the mind of an Imagineer. There are a lot of possibilities there, and with an "IP"/"Sponsor" that should be able to evolve over time quite easily.
