You would surely need to have printed samples in the space you were
encoding, as otherwise I don't see how you would make the profile.
The related approaches you may be thinking of are 'reference CMYK'
(forthcoming ISO 12647-7) where reference printing conditions are
defined (as in TR001, for example) through the measurement data for a
range of processes; and 'virtual CMYK' whereby this data can be encoded
in a profile so that 3-component data (e.g. RGB) can be exchanged in its
place (assuming that CMMs behave consistently).
