Although it is possible to grow just red and blue, allegedly some varieties require white for flowering. I have never tried without whites, I am basing that of KNNAs testers from Cannabiscafe. Removing the whites would increase your saturation and I suspect it would decrease the efficiency of the SPD. If you did remove the whites I would recommend increasing the 630nm red or decreasing the 660nm red.
The fasttech driver is good up to about 50vF. The string I mentioned pushes it pretty hard 45vF if I recall.
I have always been skeptical of the value of far red and infrared LEDs. They are relatively low efficiency and not photosynthetically active, so in theory they should significantly decrease your grams/watt yield. I am aware of the emerson effect but I suspect it may not be worth the efficiency penalty and cost if infrared LEDs are used.
Halogen floods are much more efficient at creating infrared than LEDs and much cheaper. Halogen can be used to simulate dusk at lights out, but I have never experimented with it (last thing I need is more complexity in the rigging of my grow space lol). Up to this point I have been focused on getting as many photosynthetically active photons/watt as possible. If it turns out that infrared is actually yielding more bud then I would rethink my entire approach and probably go back to HPS and supplement with blue and deep red LED.
All that said, if you are in an experimental mood I say go for it!
