It would be awesome if you could make a mask that looks the like the one from a Combat Ranger in Fallout New Vegas, check out all the variants of the Combat Ranger Armor and also all the variants of the Riot Gear, they look similiar but differences include color of nightvision lenses, overall color being browns or greens and other things such as the tubing,antennae and other small details. You definetly can do this like other items made in the past referencing such things as Assassins Creed, and better yet straight up there is already a Pipboy cosmetic item
