Raising the hitch height on the hitch is no big deal, a couple of bolts and pull it up to the higher set of holes. Doing it would be a lot easier with two people tho. I'd be cautious about re-engineering the hitch, you will change the lever arm for the worse. Call up the Pullrite people, they are very helpful, if raising the hitch isn't enough.
