The board uses two, well three actually, sources of power. Two 115vac feeds, each with their own breaker, and the 12vdc power contained in the cable from the thermostat. There is at least one 115VAC relay on the board, but most have 12vdc coils.
I agree that additional heavy duty relays would be best located outside the existing enclosure.
If I were doing the job ( I'm not as I am reluctant to fix what I fixed before until it breaks again :-) ) I would simply replace the two compressor relays with external higher rated relays ensuring compressor current is no longer on the board, and call it done.
