Only in the most literal interpretation, which isn't terribly useful. With Rome, I still build less Macemen than Praetorians during the time both are available because I'm cheap.
Naturally, I have no first-hand experience with hypothetical Macemen clones as a Swordsman UU... there would probably be issues, but facing twice the numbers in Axemen is unlikely to be a cakewalk either.
