cheater peg on crf450

Soo, what is the best way to go about this? Anyone have any ideas?
Obviously I can always change around the subframe like Ryan Moore but I need to keep this bike as close to MX as I can.

Tryin to come up with something that is removable. Any hard crash off a jump would probably end up bending the subframe (done that wayyy too many times already!)

Not sure if drilling a hole in the already too-thin subframe would work. Would ideally like some sort of clamp that I could put on the subframe that would have a bracket come down and a folding peg on it, and remove it when I'm on the track.

Suggestions?
