I don't use that inkset, but it ought to be easy to profile a PK + toner setup.  See p.5 of http://www.paulroark.com/BW-Info/Eb6-PKN.pdf for some notes on making profiles with QTR.

If you just have the PK as the only gray ink, density 100, QTR will make a "black only" type of curve.  It's a little closer to linear if you hold back the ink limit and put the ultimate one in the Black Boost.  It'll put a steeper slope on the black ink (or whatever one is the "gray" ink with density 100).  Set up cyan and blue as the 2 toners. If you want them to go all the way to the black, have their density be 100.  A lower density tells the program to turn the in down at the end.  Use the ink limits of the toners to control the final tone.

This will work but you might have banding with the R800 and only the PK with toners.  Trying to get good neutral B&W prints from the R800 with the full color inkset being used is probably a hopeless task.

Good luck.
