I was pondering that idea myself. It would work pretty well too. A system like this was just introduced in the bicycling industry. A steel braking surface for disc brakes is bolted to an aluminum carrier that then attaches to the hub. It saves quite a bit of weight, but im not sure how easy it would be to implement this in FIRST. It would take quite a bit of machining and a lot of work. I dont think it would be strong enough for drive sprockets either.
