You can dilute K4 Eboni to make Eboni/Carbon-6 inks that have approximately the same density as the industry standard LK and LLK.

See page 2 of http://www.paulroark.com/BW-Info/Carbon-6.pdf

Carbon-6, Dilute Eboni Mixing Ratios:
 K = 100% Eboni;      
 C = 30% Eboni, remainder C6 base;     
 M = 18% Eboni;     
 LC = 9% Eboni;     
 LM = 6% Eboni;     
 Y = 2% Eboni; 
    
 LK = 18% Eboni;    
 LLK = 6% Eboni;    

(Note that the density/ink-load curves are not linear and not totally congruent, and these vary with paper.  So don't expect an exact match to the glossy compatible LK densities at all places.)

See also the top of page 4 of http://www.paulroark.com/BW-Info/Eboni-6.pdf .  There is some uncertainty as to whether the LM-M densities or the LC-C densities work better in K3 printers.  It may depend on which generation of printer.  Both work as far as I know.  Which is the better choice may depend on whether you use the Epson driver or QTR.  Maybe safer to to with the darker ones for the Epson driver and lighter ones for QTR. But, again, either have worked with either approach; the differences are not critical.
