My question is, why not use a different set, CMY, so that each site captures more light?

What you gain with more light, you lose doing the matrix conversion to RGB.  Foveon has a similar issue.

It looks like a few early digital cameras used a similar CFA back around 2000 but none since.

Thoughts? Why don't we see this on cameras today?

Other than the most obvious reason: experience that RGB works better?
