What if Ken Norton had fought Vitali Klitschko (both fighters in their primes), who would have won in your view?

Vitali Klitschko is a big man, using his physical advantage, which is the size, is maybe what he does best.
Ken Norton was a very powerful man who even once defeated Muhammad Ali, a true fighter as it seems. On the other hand, he really wanted to beat Foreman, but George was just too strong.

Could Ken Norton cause another cut on Klitschko? Would Vitali be able to fight Ken from the outside? Would one fighter be able to bully around the other?
