Your questions are tough to answer...in order to answer them I'd have to somehow agree that your SPS selections will thrive under VHO's....any combination....and that just isn't going to happen. You can replace the "white" lamps with "blue" lamps and that will alter the color your eye sees...but it will provide no benefit to your corals. The montipora digitata that you keep refering to will possibly live in your current lighting...but no matter how you configure your 4 VHO lamps there simply will never be enough intensity or PAR to adaquately enhance SPS corals....I agree that there indeed are hobbyists keeping SPS under VHO's...but I seriously doubt that they ever look as healthy or grow as much or color up as well as they will under MH's. Where there is a will there is always a way...and if you intend to keep an assortment of healthy/thriving SPS corals then I'd urge you to find a way to alter your current lighting system to properly provide adaquate lighting. Its that simple....and there really is no adaquate short cut....no real viable alternative.....its just that simple.....
at least to me it is...thats why I evolved from a few decnt SPS types in a 55 gal display under 4x65 PC's(10K) & 2x110 VHO's (URI actinics) to a 100 gal display with 2x400 MH's (10K) & 2x110 VHO's (URI actinics)...plus there are other considerations.....a radical increase in circulation and careful adjustment/montoring of water chemistry. I now have a large assortment of thriving SPS types and I have absolutely no doubt that I would not have managed to advance to this point under the old system. So...as I said your basic question has no available answer other than to agree with what you'd "like" to do...or strongely urge you to consider proven alternatives to your choices.
