Creating separate workflows can make things unreliable if
accidentaly different treatment creeps in. Using a very similar
process to that used for calibration & profiling, it should be
possible to verify that the calibration or profiling is
having the intended effect in the print workflow.

Expecting the profiling package to directly interact with
the printing environment would multiply the work needed
in creating a calibration & profiling application considerably.
There should always be a method of performing this sort of task
in independent steps, both to allow a wide range of mix and match,
and to be able to diagnose what's going on.

Direct interaction with the printing environment should be possible
(for a smoother user experience), but not essential.
