Good luck!
Very interesting link.

I wouldn't increase your daytime above 14 once your 12/12 is established. In theory you could increase it more and use products such as Bud Blood and Overdrive in proper concentrations to chemically trigger the flowering horomone in the plant to make up for the reduced strenth of the flowering light signal.

Also if you go super crazy with a high intensity room a plant may become "light bleached" where parts of the leaves turn white instead of green. Simple physics of wave length absorbtion tells you that much of the light is reflected off the leaf and little light can be absorbed from this area of leaf. Just thought you should know...
