I don't think you'll have a problem at all. If you have to restrict the flow to the powerhead, restrict it on the intake side. Offhand, I don't think powerheads use the sort of AC motor that likes being connected to a light dimmer. I wouldn't take that approach.
I use a powerhead in my tank, and the plans seem to love it, and you get a lot of nice motion.
