Yours and other people mileage on this list may vary with respect to this
workflow but, in my experience, RGB profiling consistently yields a smaller
color gamut than CMYK profiling. How much smaller? I never succeeded in
quantitying it. But it is there, nevertheless, especially visible in the
shadows. A difference you can actually easily see graphically, in Chromix 3D
grapher, if you overlay two printer profiles made of the same printer, one
in RGB and one in CMYK. Watch the shape of the wireframe toward the black
point.
In theory, as long as the EPSON driver doesn't get in the way, the results
you'll get through RGB printing should be more than acceptable. And that has
been my experience with the NCA color settings. I have an EPSON 890 that I
routinely use that way and with good results, through the EPSON RGB driver.
I just started to experiment with BEST Designer Edition for OSX but I am not
advanced enough to tell you whether printing in CMYK to the 890 yields a
larger color gamut than though EPSON RGB printing.
As far as linearization is concerned, I think everyone on the list will
agree that it is often one of the key variable in obtaining good
characterization. And, let's give credit where credit is due, BEST's
linearization is among the very best out there. If you're able to replicate
their linearization, you'll be in good shape for printing to your particular
printer.
All in all, to get back to your original question, I don't think you'll get
better results by profiling through the EPSON driver.
