Just thinking out load, as a later updated board, If you were wanting to run somewhere in the future a larger separate resistor bank, could you have 2 header pins that disconnects the output drain of the mosfet from the on board resistors, but have a jumper that can be placed easily on the header pins if you wanted to use the on board resistors, you could use the drain output header as a mosfet driver to turn a more powerful mosfet and resistor bank.
