When You speaking about different color spaces, You're assuming that they are
device spaces, not PCS. Right?
As far as I know the device link represents the mapping between two DEVICE
spaces, not PCS.

I think Yes. But this may be not so straight and simple. If I find some free
time I'll try to find the sequence.

So, may be You're speaking about the conversion lilke:
DevA -> PCS -> Simulated_DevB -> PCS -> DevC
?
If You really need
PCS -> simulation space -> PCS
then You should include in this patch the conversions that are applied to
source image. The gamut mapping and (or) gamut clipping.
Can You provide the files (ArgyllCMS compliant) that describes Your devices to
experiment with?
