No no no no!!
No simulator.
I think you guys are getting too complex. The gyrosphere doesn't actually have to simulate the ones in the film exactly. Indoor, dark ride, outside portion, scary Dino's, track based is fine, but it would be really awesome if they used a trackless type system that they have at the International Disney parks.
I think you guys are getting too wrapped up in getting the ride vehicle to be exactly like the one in the film and not seeing how dead simple it could be - omnimover with a outer shell.
