Yes, and there are PS curves or other profiles out there for some papers.

That would work.

That was for the 2400 with the Epson driver.  EZW-Y is a pure carbon ink,
but it is denser than LLK or the 3D/UT7 LC.  It works well in the 2400 with
Epson driver and ABW mode because the driver is also putting LLK into the
image, and the driver uses little of the EZW in the highlights.  If I were
to set up a printer that had LK in it and I wanted a lighter ink for the
highlights, I'd use LLK (1 part LK to 2 parts base) or 3D/UT7 LC (1 part LK
to 1 part base).  The normal dilution between midtone inks in the Epson
scheme of things is a 1/3 dilution -- the is, LK to LLK.  On the other hand,
I think LLK is lighter than needed in modern printers.  So, I tend to use
UT-C to LC (same dilution ratio but a bit more dense), which gives a better
dark gray to black transition.

As a practical matter, LLK makes a lot of sense for your use.
