I agree, no need for all of the channels of light you have mentioned. From my personal experience I would only do:
Cool White
Royal Blue
UV
True violet
If you wanted to keep it simple then just the Cool white and Royal blue.

I have a fixture I built many years ago. At the time I just used cool white and royal blue with 90 degree optics. When i put it back to use over my 120 gallon tank I added in some violet, red and green emitters without any optics just to add colour. It's working really well but I've found i basically have the reds almost turned off. I don't find them useful at all.
