You can add an additional correction curve using GRAY_CURVE=
It's applied after the linearization curve so it may be a little more
difficult to see exactly the interaction of the two curves.   But with
minor corrections I think trail and error would be possible.

Another possibility would be to use PS's custom dotgain curves
and print through a soft proof correction.  I haven't tried this but
I think this would work.
