I like that idea. Given he's already got a leaf, you're probably right, he'll get bigger and the bamboo leaf will become a bamboo staff. I'm personally secretly hoping they give him two evos. final one being a little old mischievous martial arts master panda. small would justify a different stat distribution compared with the other bears (and differing design). It would also help separate him from some of the existing huge attack, high HP standard fighting tanks that are already out there. stat balance wise he could be a bit between meinshao, and hitmonlee, with hopefully a fun ability, like sap sipper/serene grace.
