To my knowledge, there's nothing that works in the opposite direction - uses aftermarket SWCs to control a resistor network. The cheap way would probably be to take apart aftermarket SWCs and rip out the logic and replace it with the correct resistor network, the clean way would be to create some new logic to use the commands from the aftermarket SWCs to control a resistor network.
Or you could just check compatibility before ordering it, and keep your receipt.
