QTR-Quadtone RIP

Hi,
I am aiming to build a system based on an EPSON printer where I could
print from carbon (warm) to cool using 7 shades of pure carbon with
EPSON LC and LM. While I am quite experienced in standard profiling and
printing and also using standard piezo, I stuck in understanding if and
how I could profile such a system.
I have a lot of questions and hope you can help :
    * The setup would be 7 shades of pure carbon + LC + LM. In the case
of Piezo inks, which I know better, I would also need GLOP and matte
black. Is such a setup "profilable" by a standard human being that I
hope to be :-) ??
    * My idea is to profile 2 tints for each paper : warm (carbon only)
and cool (through the printing of LC and LM) and then I could compute
any variation in between. I read a lot about profiling, but I am still
very confused about the way I can profile a paper for such a purpose.
Print a step wedge for each cartridge and use QuadTone Profiler to
compute the curves ? Or try to compute everything with self made
calculations, which is surely a nonsense as this work has been done
already by much more knowledgeable person ?
    * Also, better choose PIEZO Carbon inks or EBONY inks ? Which one is
better ?
That's a lot of variables, and I hope someone can help a little bit !
Many thanks
Arno
