... Besides the reversing valve you would need a crankcase heater and temp monitoring controls among other things. Capacity would certainly be limited by the existing coils.
I assume the crankcase heater would be to allow for defrost mode, correct?
Incorrect.
Crankcase heater prevents liquid refrigerant from slugging compressor in cold weather.
Nuttin' to do with defrost mode.
