http://www.paulroark.com/BW-Info/1400-Eb6-Profiles.zip now has all of the Eb4 1400 QTR profiles and ICCs that I found in my computer.  I'm not sure there is one that is directly on point, but take a look at the Red River cool profile.  What I did is make a separate profile for the cool inks.  That profile is then used with the 100% carbon Eb4 profile and mixed with the sliders.  It might work for Epson HP also.  

I don't have Eb4 loaded now, so I can't do further work on that at the moment.  If you compare the K boost for the cool profile with Eps HP and adjust that it might improve the profile a bit.  Ideally, I'd re-linearize the Red River profile with the Epson HP paper.  It's probably close enough with respect to the crossovers.

I think the first thing any B&W printer ought to try to learn how to do with profiles is re-linearization.  The flatbed method works, and it's a lot easier now with Roy's PS action to automate most of it.  See http://www.quadtonerip.com/html/QTRdownload.html and download the Stepwedge tool.  Read the PDF in that download.  Re-linearizing profiles is not hard and opens the door to all sorts of papers and custom profiling.

Hope this helps.
