I have since been told that this may not have been possible due to the auto coupling of the ailerons and rudder within large transport aircraft and that it might be impossible for pilots of these aircraft to control the rudder at all above normal taxi speed.
That may be the case during a coupled autoland approach, where the rudder is controlled by the autopilots. In fact the 747-400 (and likely others) will put in a certain amount of cross-control when the crosswind is in excess of about 5 knots.
Otherwise, the ailerons and rudder are independent, including when the autopilots are disconnected during the above-described autoland approach.
The turn coordination mentioned by 18-wheeler is a function of the yaw dampers, and is also independent of the primary rudder control.
