If the floor is out, I don't see why you couldn't add 300-500lbs of glass / lead to the hull to the center section. You would also be able to reinforce the weak area in front of the stringers.
BigFluke told us where the LCG should be from the heel of the boat (7.9ft). Notch the transom, lose the bracket, and add some weight low in the hull up front (larger fuel tank + extra glass / lead).
I think this 150gallon tank could fit. I have to measure, b/w the stringers again.

The pic is from a 23, but you get the idea where I am talking about adding weight.
