Then you would need something like the HP GO to dilute.  I don't know if it has "blanks" in it -- clear pigments -- but it probably does.  They may or may not be a problem.  Thermal printers are much more intolerant of ink characteristics than are the piezo heads.

Grey is very close to Epson LK, and Light gray is close to Epson LLK.

I'm quite certain it is, in fact, a blended inkset containing some carbon and a fair amount of color pigments.

It probably gets it's very good Wilhelm rating from the high quality of the color pigments used in the mix, as well as, of course, the carbon.  As a blend of color and carbon, it's an open question whether it's more lightfast than the MIS and Cone B&W inks.

I do agree with you that the HP Z3100/3200 pigments are impressive.
