Is there anything available for a qua-band narrowband filter like the Opt Triad Ultra?

It has the following characteristics:

  Hydrogen-beta Oxygen III Hydrogen-alpha Sulfur II
FWHM 5nm 4nm 4nm 4nm
Peak Transmission 79% 97% 87% 90%


I've got very promising results using the STC DNB on Nikon D800a with APP (attached below) and would like to push the envelope even further... Any hints on how to approach quad narrowband on a CFA?
