Hi Rick,
Yes it is possible to get the best of both world!
GCR can help, but it is not the only way to do it.
The package used to make such devicelink profile is called PerfX
Device Link Pro™. For RGB to CMYK you can set many options for RGB to
CMYK, like converting neutral RGB value to Black only. Since
Photoshop CS4 seams to be locked for CMYK to CMYK only, I am using an
other tool called PerfX Color Server TIFF™, which fully supports ICC
devicelink profiles for RGB to CMYK and CMYK to CMYK.
You can send me a small image offline and will convert it so you can
see what is does.

So if it did support RGB-to-CMYK device links, then it would be
possible to set up a conversion where you could map non-neutrals to
one normal profile, while holding neutrals to the mapping of a
Maximum GCR profile? Interesting. Can you describe more how you
would set this up, and what control it would be possible to have
for interpolating the near-neutral areas? And with what device-link
package?
I've been doing this with actions, but am not completely satisfied
with the mitigation of the near-neutral areas that don't fall
clearly into one domain or the other.

Anyone got information or detailed spec about ICC DeviceLink
profile support / compatibility with Adobe Photoshop CS4?
It seems to work only for CMYK to CMYK, not for RGB to CMYK (to
keep neutral RGB on the K plate for example).
Also, be careful to Assign the output profile (used to create the
device link) in order to get accurate preview after the conversion!
