I wish they'd bring back the museum that used to be on the lower lot and expand it somewhere. I think I've said it before, but there's so much history (props, costumes, and beyond) just sitting and collecting dust, and a walk-through museum with a few themed rooms along the way for bigger IPs (Jurassic, BTTF, Jaws, etc.) where guests can do photo ops with props, animatronics, or even an occasional character actor would be a great way to collect a lot of the studio's legacy in one air-conditioned place year-round.
