I was thinking along similar lines but for space and stability reasons. What I had in mind would be to use plywood to make the bottom of a Putz Walrus and hopefully come up with something rigid enough to skip the floor beams. Build the rest of the frame normally and skin the whole thing. This would leave more room for big feet and lower the seat an inch or two. Not that this would help any when you ram a rock but maybe you can epoxy the skin (poly?) right on to the plywood.
