Sorta like Macready's duster's lower part separated into a wearable sash thing, along with the Grognak sash and the other coats in game. I'd make it myself but I'm not sure where to even start...
How about; Timed Blocking for the Ricochet perk? Like a Jedi deflect... Maybe a script that makes the ricochet chance 100% when blocking (since you can't hold block anymore) Would leave a little bit of skill in it since you'd have to try and block soon as they shoot you.
