Not sure I understand. If it's panelized and it's Lutron, all of their keypads will work. Just double up pairs on the cat cable and you shouldn't have a problem unless the wire run is over a long distance (200' or longer). If it is longer, bumping up to 36v would be helpful.
So long as you have access of that cat cable running over to the lighting control system, you should be good.
