Wow. I was at Lowe's shopping for ratchet wrenches this evening, and thought of essentially the same thing when I looked at the flex-head wrenges. I was thinking of using a non-flex head, non-reversible wrench, wedging it in a piece of aluminum channel (similar to your two bolts), and lifting it out parallel to the shaft. If you do this, be sure to mark the ratchet wrench as to WHICH SIDE FACES OUT, or you'll have a useless climber for a match or three.

I concur that with the rules as currently written, it would not be legal (Drive team damage vs robot damage). However, given the preamble to the answer to Q299, I suspect that a question on this topic would get a finding of legal even if it meant a rule change.
