  Quote   I don't see why the thermostat can't run the load as normal?

Yes, as long as the switching 'on' time is short enough to prevent excessive burning and the 'off' time long enough to extinguish the arc. Or the thermostat could switch the MOSFET gate, with a resistor to source to ensure it switches off.
