The only way a gyrosphere ride could really work while maintaining any sort of decent capacity is either using four-person RVs (at which point the size of the RV is untenable), doing 2-person RVs on an omnimover-style system (think Spaceship Earth) or 2-person simulator pods. Either tracked option loses potential interactivity while the simulator (in my mind, the most efficient option) is a simulator.
I really think the ride mechanics are the easier part of the ride, especially if it uses DisneySea’s 2K League wet/dry tech to simulate rolling while it’s actually simply on a gimbal. The challenge is that the gyrosphere, because of the shape, needs to be roughly 7-8ft in radius to fit two (average) people. Large people, it’s closer to 8ft. You can easily fit 4 people in a box that size, or 6 if you cram them. The capacity is the major issue.
