Hi Roger,
Since a CMYK seps is directly related to the TIL and black
generation, a CMYK to CMYK is required.
Curve only approach will always break the color relationship (CMYK
seps).
To do so, for example, we have built a PDF color server which can
apply such TIL reduction to image only elements with ICC profiles
(not device link).
Very useful to manage such issue when needed.

This is a question that's more print-oriented (sorry Edmund).
It's about bringing down the total ink coverage in a CMYK image
from, say
350%, to 280% for publication work for example or, even more
drastic, down
to 240% for newsprint work. The issue arises constantly in print
production.
I know there are superlative tools out there like Alwan CMYK
Optimizer that
do this kind of job as part of their toolset but isn't there a way
to reduce
the TIL in a separation without going through some CMYK to CMYK
conversion?
Whether it'd be done through optimized device link profiles or just
through
a pair of ICC Output profiles?
I confess my ignorance here.
