Dave, the Hot Rod Cams and a SC grind are two TOTALLY different things. To get the lopey idle, the Hot Rod cams have a longer duration. That duration with a supercharger COULD be devastating. That is why Brenspeed makes SC and NA grinds for their Detroit Rocker cams.
And, as I said before, mating the right cam with your supercharger will give you the best gain. If you're going to spend the money and time, might as well do it right.
