I agree that a D800EM would have a limited market, though probably bigger than the Leica MM depending on the price of a D800EM. As far as modifying an existing sensor, I have heard of successful experiments to remove an Anti-Aliasing filter. However, I have not heard of any successful attempts to remove the Bayer filter array from an existing image sensor. This part of the operation would require a physical operation at a microscopic level. It may not even be possible considering the process used to put the Bayer pixel filters in place. As you point out one would also have to modify the software algorithm in the camera processor which in a digital color camera uses the light values from eight adjacent pixels to calculate the likely color of each pixel. Without the latter modification the camera would still try to give you a color image except the colors would be based on completely erroneous information from the pixels. That's why I am leaving my D800E alone, hoping that Nikon might bring out a "simplified" D800EM for high resolution, high ISO, B&W photography. It sounds like most of you would not initially buy one, but I certainly would.
P.S. Here is a recent statement from Panasonic: Blame the Bayer filter for your camera’s poor low-light performance, says Panasonic.
