They already have! The Moon Astronauts had an internal conditioning system that pumped comfortably warm water around their suits to stabilize the temperature. Outside, temperatures varied from +200 to -200 centigrade, but the guys inside the insulated suits were just cozy. On a Moon Suit, that big boxy structure on the back and behind the visor is the heat exchange system - it's really big and very powerful!
