That's a good idea, though maybe the damage against champions could scale with AP plus a flat amount, but against minions it's true damage. This way, his jungling and laning are kept strong without being absurdly powerful. Reduced damage against champions would work well, too, but I have a feeling it wouldn't scale all too appropriately throughout the game. It can most certainly work, and it would introduce a new element to countering Nunu: getting health items early on. When I think about it, people would likely stack Doran's Blades if laning against a Nunu down bottom to counter his true damage, which would effectively hinder their late game.
