MIS has a page at http://www.inksupply.com/roarkslab.cfm that they 
include some information on mixing inksets.  It is not written by me, 
and I disagree with what might be seen as a suggestion to use 
their "UC Base" to dilute PK and perhaps even Eboni.

With respect to glossy inks, I've found the UC base produces terrible 
bronzing.  With respect to Eboni dilution, the UC base produces 
images that band (see 1600 dpi scan at http://www.paulroark.com/BW-
Info/Base-comparison.jpg ) and are warmer than the base I recommend 
for Eboni dilution.  Additionally, the specific gravity of the UC 
base is low, suggesting that it may not hold pigments in suspension 
as well as the others.

Don't use Eboni for glossy paper.  We're working on a possible 
workflow that will allow this, but in general, stay away from 
diluting Eboni for glossy printing or with currently available 
dilution bases.  Hopefully MIS will have the correct base soon for 
the Eboni-6 inkset, which is a dilution of Eboni, but for matte 
papers only and not to be mixed with other inks.

Start with MIS PK.

> - base to diluite and obtain shades of gray

Use MIS Gloss Optimizer as a base for glossy printing.  It will also 
work for matte paper printing.

> - glop to diluite the balck in one channel to use with glossy papers

Yes, glop and PK are compatible and make good midtone grays for 
glossy or matte paper printing.  You will, of course, need Eboni or 
other MK in the printer for a good dmax on matte paper.

> - blue toner to neutralize and cool tone the print

The blue toner is a mix of cyan and R800 blue or magenta.  If you 
have 2 channels, simply using LC and LM works.  That way you can vary 
the ratio as needed. 

Good luck with the project.
