just don't mix the old silica based (green) coolant with the new extended life OAT (pink or orange) coolants otherwise your radiator coolant will turn into a slushie.

I would think so.Drain and add to the radiator doesn't replace the coolant in the block until the engine runs long enough to open the thermostat though. So you could have a radiator good to -30 but a block that still has -5 coolant correct?
Fire it up and run it a few minutes. There's a bypass hole so the coolant can get through in the t-stat. Some motors even have a bypass hose for when the t-stat doesn't.Drain and add to the radiator doesn't replace the coolant in the block until the engine runs long enough to open the thermostat though.

Engine block heater will solve the problem, not that anyone in this part of the country has one.
