Something's been on my mind. For combiners, most of them have a large "body" figure and 4 limbs. Now the arm bots generally turn into the entire arm (upper arm, elbow, lower arm, and hand). But the leg bots only turn into the lower legs and feet. It seems to me that is the reason the body has to be a larger sized bot; it has to also contribute the upper legs. So why don't the leg bots also form the upper legs? Wouldn't that allow 5 bots of roughly the same size? It would also allow the leg bots to have a more interesting combined mode than vehicle mode sandwiched between foot and thigh. Just something I've thought about.
