Actually thats how I process monochrome pics with narrowband filters. With red HA filters I delete the green and blue channels (and the noise that accompanies them) as theres no signal to speak of. With the O3 shot, however there is about 1/2 the signal in blue as is green, so I reduce the blue by 50%, green 100%, red is completely deleted.
technically the colour digicams are indeed rggb

more green then red or blue pixels
This sensor type sounds like a good design, but sadly doesnt yet seem to outpace current DSLR sensors
