Digital BW, The Print

Hi,
in my last post I got advice to maybe try http://www.octopus-office.de/shop/details/c/tinte-nachfuelltinte-epson-t0540-t0549/p/ocp-optimizer-fuer-canon-bc-60-farblos/
to mix an inkset with HP matte ink. Can I really print on matte and glossy with this same ink?
Is it possible to use this base and dilute any carbon MK and use it in an epson 1400 or 1430. This would be very cheap and everything is available in Germany or will I get clooging-problems. Maybe I can even use a MK ink from OCP? This would be an open source european solution.

or maybe I can take the claria substitute from ocp and make six dillutions with the ocp with that. Could be great for glossy prints, is that possible?
