I think you are on to something. But instead of a whip. How about tear gas to quickly move all passengers to the absolute rear. Instead of trying this underdimensioned hand crank.
Also remember that this hand crank is the same on 737NG (it's not new to the Max, AKA 737-8). So all those pilots better be lining up for the gym now anyway.
