Difficult question.

If the round pin is on the power supply with a mating flat pin on the head, you could replace the head connector with a round pin connector. That is just a question of mechanical comparability, since the power supply is known to be able to handle 300W bulbs.

The main problem would be that the round-pin plug is not a standard configuration. It's a special, probably not available except by cannibalizing one from a junk head.
