QTR-Quadtone RIP

Apologies if this topic has beed aired, although I couldn't find it.

I am using W7, CS and Epson 2100.

I have just downloaded QTR and been reading all the comments.

One that crops up often is that the Epson PK black is too warm.

Is the simple solution to just remove the Epson PK and replace it with MIS Eboni Black, leaving the rest of the Epson colours (M,C,LC,LM,LB,and Y) in place, or maybe even replace the Y with GLOP ?

Is it this simple - if not, what would be the procedure and how would this be dealt with in QTR.
