For WDW, it's too late. I can't imagine they'll do anything out there, and so much of it is already ingrained into the ride already.
For Disneyland? There might be time to add some stuff, or get an emergency team of different designers to redo the queue graphics and plus up some of the weakest parts of the ride. I doubt there's time to add any new animatronics at Disneyland, or change dialogue or music or projections.
At best for Disneyland, I think we might be able to get higher quality graphics and decor pieces, but that's about it.
It's just too late. The cake has already been baked, to use an Employee Owned Food Cooperative analogy.
