The concretisation from a simple to a full separated or complex colour 
space could allways be possible. This allowing: CMYK -> CcMmYK, while the 
linearistation can be done optionally with CMYK or CcMmYK curve profiles.

My experience is CMYK plays basically well. Others stated even RGB 
corrections could be ok. For utilising most of the available gamut (within 
the mathematical limits) n-colour separations with according linearisation 
seems a better choice.
