Look man, I just tried it to confirm. I did Vegito with your custom stats with Oozaru with his custom stats. Vegito beat Oozaru, it was a close fight, but Vegito won. But to make this tournament fair, I think you guys should do Best out of 3. This way it gives your fighter a chance to see it he can win
EDIT: If you guys want, I'LL do the match ups as well
