electric furnace to heat pump

CWH150

Just bought a 1500 sqft home with a 1977 electric (20kW) furnace. First project was duct sealing and wrapping ducts with insulation. Next step is a 3T Heatpump.

Currently there are dual 60Amp breakers feeding furnace. I need single 60Amp service for blower with 10kW heat strip backup. Then 30Amp service to outside compressor.

Would it meet code to repurpose one of the 60amp wire pairs using a NMEA 3R enclosure with 30amp breakers/fuses? Then run 10AWG to another NMEA 3R outdoor disconnect at the compressor. This would help me avoid digging into the panel. THX
