Why? How about something as radical as upgrading and reopening the Life pavilion to the paying guests who pay for its upkeep?
Okay, now you are just being crazy. You are actually suggesting using the already existing building, that would only need updating. You obviously have no imagination. (just kidding!) That would be a great idea, but since we have not seen anything happening in that direction for years now, it would be nice to at least save a good attraction.
Putting it in the Captain EO theatre was another good idea.
