Custom designed heat pump would make sense, but probably not easy. Lots of differences compared to, for example, my Model Y:
— fewer human bodies to cool or warm (btw, seat heaters may be more efficient/effective than cabin heating)
— smaller, tighter cabin with, probably, lower heat/cool through the body (composite vs metal)
— lower motor cooling loads (if air cooling is not enough by itself)
— smaller battery to cool/heat (in most cases)
— May be relatively larger windscreen to defrost/defog.
As an engineer, this would be a great challenge!
