CMY + RGB Color Filter Array

Wondering about the possible merits of a hexachromatic CFA, one that sample more points along the visible light spectrum rather than the typical 3 RGB.
Is there any reason why such CFA scheme has not been tried?

The benefits to that approach would be.

  • Higher Color Accuracy, specially skin tones. RMY
  • Higher Dynamic Range
  • Higher Sensitivity due to CMY
  • Less noticeable moire artifacts given the wider spread and more complex pattern.
  • Probably more resilient to IR contamination, IOW better Reds with the help of MY

The only disadvantage I see is more complex processing algorithms but given today processing power that shouldn't be an issue.
