As an Examiner I am far, far more interested in sound basic IF skills on the IMC Rating test than I am on anything more than fairly basic radio navigation. Yes, you can organise a small route if you wish - I prefer a simulated SID to VMC on top, then the IF manoeuvres with the applicant 'under the hood'. When we've finished all the UP recoveries and limited panel work, I get the applicant to settle down again on full panel, intercept a given radial and track towards the beacon I've chosen - then fix position, estimate a heading to the aerodrome for recovery and then to get on with a radar vectored ILS, go-around, NDB approach and go-around into a low-level visual circuit to land.
The 'route' requirement was going to part of the proposed Instrument Weather Grading but that was binned by industry.
