As it sits, that is a 56 non AC pad with the wide slots for the brake supports. 55 brake is similar if not the exact same mount and pedal arm as 52-4. That mount is shown in the photo below. You mentioned accelerator but that did not change. I do not know if the pads have embossed locations for the added AC holes but don't remember Stewart mentioning any when he was talking about this same pad a few weeks ago.
If they did embossing for the AC holes and the 55 brake support locations so the buyer could cut the holes, conceivably they could get away with one pad even with the 56 slots already cut. On all but the cheapest models a strip of carpet was glued on the bottom half of the pad and would cover the slots if not used. A strip could easily be added for the low end models but the slots are small and high enough they may not be that noticeable. As it currently ships, that is not a one size fits all pad.
In AC cars, the R air vent is not used so the AC evaporator case covers the right side vent hole and in the field install they put a metal plate over the vent opening on the firewall to block air. Have not seen a new AC car pad to know if that green vent hole opening area was there or not but I suspect not. With a plate covering the firewall opening it could be cut and the carpet strip would cover any of the opening not covered by the evaporator in an AC car.
One other issue on having one pad fit AC and non AC would be the clearance holes on the insulation side for the various added and different locations for screw mounts for the evaporator and valve. They would need to have all of those spots cut away in the insulation portion for both models so the pad could slip over them.
The hole for the heater valve is the same on all cars but on the inside under the pad, the screw locations that hold the valve are different because the valve body -- not the tubes -- is what is angled.
Here is a page from the AC field install book showing where the AC blower and tubing holes are located. Maybe there is enough info you could find the locations on the pad. If you want to see what all changed on the valve and added screw mount locations there is another photo in that book that shows what is needed to mount the standoffs for different screw positions.
