What I was referring to is blue sky. It would completely mean razing the entire existing attraction to the ground and not reusing anything. It's what the area needs and what the paying passholder and day guests deserve.
If they wanted to do Pets, they could do it without the loss of the Supercharged building, nor removing a singular attraction (In-Between Supercharged and Mummy, replace Louies and move some of the backstage buildings right there and you'd have a plot similar to that of Pets Hollywood). But that should be a discussion for a different thread.
With The Bourne Stuntacular proving something important, practical car moving alongside screen = win. I think the 360 Arena, would benefit honestly from that of practical cars rising up and down the sides, as if they're exiting off of freeway ramps and driving alongside the cars. Simulate the sense of speed by having the cars alongside you and in the process, their wheels moving at fast rates to match that of the digital film.
