How to move Volibear from the early game to the Jungle

As a note, I had this idea late into the night while cackling over my computer like a madman. It obviously has it's flaws, but maybe there's something to be had from it, whether it be on Voli or some other champ.

To move Volibear out of the early game and into the jungle while trading his strengths rather than nerfing them, I think the answer lays in his passive. The current issue many of us might run into with/against him is that his early game strength is overwhelming, but leads to a slow and painful decline in power. To fix this, I propose that his passive be changed to make him more of a bear. Make this cozy beast "Hibernate" when he's farming a camp in the jungle, healing so long as he's unseen from the enemy team and staying (relatively) still. This would keep all of his sustain and even more than that's given by his passive now, and gives him a purpose outside of dominating lane for five minutes as a support or top laner.

So, what do you guys think? This clearly has issues, but I dunno, I think it could be used somewhere. Comments? Further ideas?
