A very good video on upset recovery, stalling, and most importantly, Stalling while Skidding, and slipping.
Not once is anything mentioned anywhere about picking up a wing drop, let alone using aileron or rudder to pick it up. Slipping at the point of stall is nothing to worry about, Skidding on the other hand will kill you at low level. and both are demonstrated here.
