That might work. I thought about getting one of the heaters that circulates warm coolant through the heater hoses, but I chose the OEM style screw in heater instead to avoid the extra bulk, complexity, and points of failure.
I think the remaining pressure issue may be caused by the block heater boiling the coolant and creating steam in the system. The outside brass part of the block heater gets hot enough to boil water within seconds, so I bet the inside gets more than hot enough to boil the water/coolant mixture.
