It makes sense. Though a plant uses more of a red/orange spectrum during flowering. Im sure the added blue/green spectrum will make a difference to some point. Ide stick with the 600. If you want a mixed spectrum then just add a MH. No sense in getting a product that costs more when the two seperate are cheaper. Doesnt need to be much, lets say 250watt. Thats 250watts MH and 600watts HPS....Sounds like a good spectrum to me.
