sorry. dont understand what you are trying to do. a planetary gearbox? or a gearbox within a wheel? the latter i know some team has done. maybe a few. and a plantery gearbox. well i would have to say makeing one will be a pain in the butt but its possible. although i dont understand your trying to spin things in two directions comment... basically for a planetary you need a ring gear, a center "sun" gear and well to make it work well the minimum of 2 "planet" gears. the center of the ring and sun gears should be exactly the same and the planets should be touching both the ring and sun gear.
sorry if im explaining something you already know.. can you be more specific?
