Thanks a lot for all your information Gerhard!
This is exactly what i wanted - colorimetrically correct ink-limiting
while preserving black-generation as much as feasible.
(Well, in some cases reprofiling from measurements may be useful, of
course, to optimize the new profile for the input gamut.)

Hm, that anticipates my next question. So, no luck, it seems. :-)
Such a tool might make a nice addition to Argyll one day. ;-)

Thanks again,
