Those look superb!
Thanks for sharing them with us.
I'll have to see if I can think up any others.
About the only thing I can see adding right now would be perhaps some sort of a negative consequence for winging, or severely wounding an innocent third party. Obviously, if you accidentally, or on purpose, happen to kill one, while trying to take out an opponent, that would be even worse.
Say perhaps 1DX persons turn against you, and fire on you, if they are armed, or they run you out of town, if you wound an innocent person.
Should you kill a woman, child, or other unarmed person, even more turn against you, and they'll send a posse after you, for a neck stretchin' party.
Can't recall if TRWNN have accidental/incidental casualties, if you miss your target, or if someone is partially in the way, but if so, the above could make things a lot more difficult to have a firefight in a crowded location, like a saloon, city street, general store, etc.
