LOL on the heavy press cap!
Got to thinking, as I've seen custom wall paper from pics. Just a quick search and this popped up. https://www.megaprint.com/wallpaper.php
Here is a link to the pricing...don't know the size of your wall. https://www.megaprint.com/prices-sizes-prints.php
This is for a 8' x 12' smooth wallpaper. Not bad $$ for an all out man cave, but I would have to chat with them about resolution.
Another possibility would be a Halftone printing of some type where the resolution isn't as high. Old school but still around.
P.S. let me know about the PM I sent, and I'd be happy to prep the artwork for you.
