You've hit all the high points, especially about pulling the plugs, squirting some oil or penetrant in the cylinders and turning it over by hand before trying to start it. You may want to see what's happening in the gas tank. That could be a problem with some really stale fuel or some combination of really stale fuel and a mix of water and who knows what else. If there's junk in there, it will probably not get past the fuel filter, or at least not for long.
I'd say give it a shot. If the fuel isn't completely turned to molasses or full of water you may be able to fill the tank with fresh fuel and get by.
As Dirty Harry once said, "are you feeling lucky ?? "
