In this case since the MAN PITCH TRIM is available, you could configure the airplane as you normally would.
That's true. As I said if stab is jammed only then. However many instructors teach to lower the gear after flap3 even in case of Dual RA. According to me this doesn't serve any purpose except postponing direct law by may be 15 seconds. Since you are going to fly in direct law till touchdown these 15secs should not be such a problem. According to me there are only two cases for non-standard configuration i.e. G+Y 1,2,3 and gear down and G+B gear down 1,2,3.
