How can I reskin the Headband of the Ninjitsu for a steampunk campaign? [on hold]

My DM is running a steampunk Pathfinder campaign, and he’s banned strictly magical objects and weapons. However, he has said that if we can reskin it to fit within the world (i.e. a wand is more akin to a blaster weapon, weapon enchantments are things like batteries and small jars of acid strapped to weapons, that sort of thing), then he will allow them.

He has very recently given us a large wad of cash after we captured a terrorist alive and presented him to the local military. I would like to purchase a Headband of the Ninjitsu for my rogue character, as it gives bonuses to stealth and sneak attack rolls. I’m not certain how I would reskin it to fit within the world, or how it would give me those bonuses.
