The use of rudder was never intended to 'pick up a wing' at the stall....rather, it was meant to prevent further yaw. A stall condition plus yaw was a potential recipe for a spin entry. Thus stall recovery, as taught in the Royal Air Force, was stick forward to unstall the wings whilst simultaneously increasing power and rudder used, if neccessary, to prevent further yaw. That is all. No mention whatsoever, of picking a wing up.
Use of aileron to pick the wing up runs the risk of further stalling that portion of the wing around the aileron and was verboten!!
