I have used 1st Gen night vision equipment and can tell you it's rubbish.
On a perfect full moon you could pick out a field, but on a full moon you can see well enough with bare eyes, assuming reasonably dark-adapted eyesight and no cockpit lights.
2nd Gen aren't much better.
3rd Gen NVGs would do the job fine but they are expensive; a few grand, and cannot be legally imported into the UK, and cannot be legally sold here either (other than to military / law enforcement obviously). Sure you could get them (hint: they are openly sold in California) but are still pricey and anything less than 3rd gen would be a waste of time.
The other thing is that cockpit (instrument) lights would completely fog out the NVGs. Mil aircraft designed for NVG ops have special instrument light mode for this purpose; too dim to see with the naked eye.
So to land with 3G NVGs you would need to switch off all lights, including external ones.
As a last resort thing, I am sure it would work. But pricey, and you'd need to have them handy!
Personally, I will fly high over the Alps with the tops shrouded in cloud but would not fly on a pitch dark night, and avoid night flying anyway.
