there actually might be a way to do this, if you go into first person view mode and unsheath your weapons, you can see them as if you're playing an elder scrolls game, but attacking with them causes them to disappear, I don't think this is accidental but I also don't think aenet would fix it either.
If you could make a program for VR that works the same way that DS4 works (by mapping keyboard inputs to the controller), it might be your best shot. All you'd have to do is map head movement to mouse control (when in action cam), and the fighting controls to the hand gear.
It's crazy talk, but with a little bit of innovation, it is very possible to frankenstein a VR experience for GW2 together.
