I'm on Salty's side, except I don't agree with Salty on all points if that makes any sense. To me, this is really simple and everyone is making a big deal about it.
I'm not an IFR pilot, but I'm very familiar with the terrain of WV. With minor exceptions, the only roads with straight stretches longer than about a half mile are the north-south interstate, I79, and the old WV turnpike that's now I77. There's not a lot of straight or flat in WV.
So...you're stuck above a solid layer that was predicted to not exist, welcome to kinda Northeast weather. You don't have enough gas to fly to flat happy Virginia or PA. You're absolutely sure you can follow an IFR clearance and break out at 3k feet AGL or whatever. So you setup to do that, and TELL ATC that's what you're going to do. That's an emergency. ATC are great people, but they're going to follow the rules. What you need to do is get down and stay alive. Best chances of doing that in that state is to find an airport and fly a published approach if you don't have the terrain memorized.
I really think this is a good question to ask...because as private pilots we should have a plan A and B, that are all happy and don't require an emergency, but if you're stuck, admit it, tell them what you're going to do, and to it. Oh, last bit of trivia? Unless things have changed a LOT since I was there, not a whole lot of low level IFR traffic in WV. Panhandles and Charleston area excepted. My bet would be that ATC's concern would be you flying into a mountain as WAY more likely than hitting any other aircraft.
If the same scenario played out here in the NE, and I were anywhere close to Albany, that's where I'd go, because I know wide areas in the Hudson River valley that are flat. I admit being stuck, I tell ATC I'm VFR and stuck, and going to descend though the clouds straight, then ask for whatever help you need after I get to VFR weather. Will I get yelled at? Maybe. Will I fly into a mountain, run out of fuel, or hit another aircraft? Nope. All that said I don't do VFR above a cloud ceiling because I'm a big baby when it comes to risk, so I look to get down and land before things close up if that happens. But it doesn't mean I won't get caught sometime.
