"... and then they both said sorry to each other and everyone was best friends."
If this is wanted / needed, the hat would be simple and easy to do. Should the clothing be a re-skin of the leather armour, perhaps, or maybe make the armour as a new model and try to transfer it to a Fallout style palette? I think there's quite a bit of design freedom for whoever wants to try at this at some point (as said, if it is actually needed).
I'd also suggest that if something good is made for this, it's also adapted to the "NCR policeman" model. I've never been much a fan of the existing "stick man" ones.
