Sounds ok to me. I did effectively the same thing on my Willys by placing 2" square rubber pads @ each bolt site. The rest of the floor is above the frame by the thickness of the pads. Might as well be a foot! Only coonstraint I would make would be to put a stand and bolt @ every site that the factory did. They usually did things for a good reason.
