You could drill a small hole in the thermostat plate to allow some coolant to bypass it all the time; I've done this when not running a heater core. It's best to run the water pump all the time, so as to keep some positive pressure inside the engine (particularly important in the area around the exhaust ports and the spark plugs), and the bypass acts as a restriction to allow some flow through (preventing cavitation) while maintaining pressure.
