Neither have I, and I don't really see how adding a growth stimulating light would benefit a flower-oriented yield.

Is there any problem with using the HPS all the way through. I have a 600 watt hortilux bulb in a sun systems fixture.

Nah, not really a problem. It is better that you use a HPS all the way through rather than a MH. The MH really only shortens the growth period and makes your plants a bit bushier with thicker stems, but only marginally.
