I think Roman could possibly put up a fight against Raphael, but lose. I think Michael would simply obliterate Roman. Michael was seen on screen, using his powers, exactly once for like 5 minutes, and he already proved immensly powerful. Not to mention, the battle with Lucifer was supposed to scorch 1/3 of the earth.....Roman just doesn't have that kind of power.

Not to mention, unlike Angels, Archangel's powers are entirely intrinsic to themselves. I doubt they can be "interrupted" or interfered with like Angel's powers can.
