Can Chowgath get back the shorter cooldown for ulting monsters?

I can't remember all the times that I've gone for dragon with , nommed it, and then a fight broke out in mid/river that I didn't have ult for at all. And I remember how Cho used to get a shorter ult cooldown if he had used it to kill a non-champion (monster/minion). Would it be that much of a buff if he were to get some resets on his ult? Perhaps you could pair it with a mechanic that either makes 's active reduce Feast's damage or his Ult ignore the bonus health from the active.
