Maybe these would be allowed, they are ANSI approved. They appear to have two lenses, an approved clear cover lens, and an approved shaded lens (which is way too dark for anything but oxy-acetylene weding, although too light for electric arc welding).

they are not "steampunk", since being "steampunk" requires adding a bunch of random junk to something.
But they might be the look you're after, in a way that you can actually use at a competition.
