I was thinking about plastic welding the cracks then maybe using the GOO to help smooth the bad spots. I think will copy the skid plate, but with maybe a little thinner material. My frame is very straight and heavy so I won't be reinforcing it much. As for the re-body option, I am not thinking of doing that to the trainer. I was thinking about future 6x6s that I might find. I have past up a few that had a complete drivetrain, but destroyed bodies.
