Well written article!

You might be interested in a signal processing scheme related to your cascading a comb filter with more "conventional" processing blocks. What the comb does is to place notches between the bands you are trying to filter apart, thus increasing separation.

In certain color blindness cases, the red and green cones responses in the eyes are overlapped so much that red and green is perceived as brown. Placing a notch filter between allows many with this condition to see red and green. The filter is made by a multilayer dielectric coating of various indices of differing thicknesses, essentially forming a "DSP filter for light". A commercial product is now sold to accomplish this filtering. (EnChroma.com).
