The adverse yaw portion of my first message is correct, the roll-yaw coupling portion isn't.
You are correct, as the rudder is deflected at knife edge it should change the amount of induced drag created by the surface, and thus cause the nose of the aircraft to move in pitch. However, this will be quite minimal, and usually in knife edge you have top rudder (if you are standing on your left wing, right rudder, the one on 'top' of the other) deflected, which is similar to the upwards deflected aileron.
If you want to find out, come out to LA and we'll give it a shot.
