If I took three diodes, either RGV or RGB, and placed them in a single house, could I not simply shine them through a mirror or lens that would point the beam at a single point? 
I would not expect it to have a low divergence, as the colors would surely separate after a long distance, but why could a simple white laser not be possible?
(I saw a laser RGB laser light show, the light frequently overlapped into a white beam)
