High Altitude Waypoints

Greetings,

If I file an IFR flight plan with the equipment suffix of /G, indicating
GPS, can I use a high altitude waypoint on the flight plan even if I'm
flying in the low altitude structure?

For example, flying northwest from Las Vegas, filing from BTY VOR (Beatty)
to DOBNE to BIH VOR (Bishop) takes me around the Saline MOA that is in the
way of a direct flight from Beatty to Bishop.

The issue is that DOBNE is a waypoint in the high altitude structure and I'm
filing for 16,000' or maybe 18,000', in the low altitude structure.

Thanks,
Dennis
