I did not notice a problem when I was doing this with the 260.  In fact, I
initially thought that OEM Claria inks with Eboni might be a great
combination.  However, I was very un-impressed with the built in profiles
and cost of the Claria inks.  So, I may have pulled the Claria and put in
MIS color too soon to have noticed any problem.  

I would be suspicious that the dye and Eboni would not mix well.  I had
problems with Eboni in an old 1280 that had dye on the pads.  The problem
didn't clear until I rinsed the dyes off the parking pad.  In general, Eboni
is said to have problems with dye inks.

It's very possible with QTR.  See http://www.paulroark.com/BW-Info/R260.htm
(Can you still get 260 carts and chips?)
