I was hoping to
focus on the mechanics of accepting a direct clearance that one could
not otherwise navigate without a VFR GPS. I'd like to have a better
idea of the legality and (more importantly) the advisability of flying
in that situation.

First off I am an instrument student, not yet rated. I have a lot more
marine navigation experience than aviation IFR experience, but let me
throw this out.
It seems possible to me to fly direct between most any 2 points, off
airways, without vectors, using 2 VOR's and a sectional chart. Just
plot a series of radial intersections at appropriate distances from
each other to ensure remaining close (for gov'ment work) to the
desired direct track. Is this illegal? Or is it just that you won't
get a clearance using this method? I am assuming that the direct
course & altitude would be within reception range of the (2) needed
stations.
This would require a bit of OBS twisting for sure. You would use your
VFR GPS to reassure yourself that you are on that desired track. If
anyone asks, your primary means of navigating were by use of VOR's.
