There's a guy on another site that can pull off an accurate as fuck Solid Snake, of The Boss timeline.

It's made all the more easier that he lost an eye and wears an eye-patch and smokes. So all he needs are the fatigues. And presumably with some more age he might be able to glue a rock to his forehead and become MGS5 Snake.

And then when he's 70 and could become Old Snake.
