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.
From my experience, that is much easier said than done (with the non-flexible non-reversing). The wrench always wedged itself pretty tightly against the stop and we still needed to lift or rotate the robot slightly to get it out. There needs to be pretty much no load on the wrench to be able to slide it along the shaft to get it off (or far enough along the shaft to not be impeded). Granted, I've always done it using two bolts/screws as the stop, never channel.

I'll second the comment about marking which side of the wrench needs to be facing out, or which way the switch needs to be flipped if you're using a reversible wrench. Drill it into your pit crew's and drive team's heads. You can never double-check too many times.
