While the final stage gears might not be able to take the stall torque generated by the 775's, the ratchet means that the motors should never need to be be stalled.

It's not even just stall torque - it's torque under load, particularly with the long cantilever on the shaft. Pulling your robot up with one of these should work for awhile, but before you know it, you could snap teeth on that pinion gear, fall from the tower, and lose your regional. Happened to me in 2013. Still bitter.
If you could somehow double the face width of that gear (second pinion / output gear) that would help I think. Maybe you'll be okay with this, I dunno.
