Part of me does sort of like the idea of having a ITTBAB/HISTA 3D show hosted by Tony Stark (Robert Downey Jr) showcasing the numerous inventions being made by Stark Industries for the future and S.H.I.E.L.D. Throughout the show we could get cameos by various Marvel characters. Bruce Banner appears as a scientist half way through the show, and accidentally hulks-out, and runs around the theater. Thor and Captain America show up to stop him. Maybe make it a panoramic 3D film, with screens all around the audience.
Make it a 10 minute show, and replace Captain EO. It wouldn't be anything revolutionary, by any means, but it would still be fun.
