Good question. If I understood it right the only part on Sam that moves is his leg from riding to breaking, his arms aren't articulated (someone will correct me if I'm wrong), so you could have the upper torso be one solid piece with an overlay, powered by one set of batteries. With Iron Man figures that have articulation you have multiple batteries needed which creates a bit of an issue. If I'm wrong though, then it's a bit more of an issue. If Sam is set up to shine complete as if he were a regular figure with no issues at all though that means that nothing is really stopping HT from making it except the thoughts that it won't sell.
