Dueling

So I was doing Midnight's quest to see if there was other possible encounters, when suddenly I have the idea of redoing it on first person. The answer was yes, you can duel in first person and is more easier to aim fast Gunslingers like Midnight or Calloway, not that at this point a lot of ppl have difficulty dueling but just wanted to share this.

So, aside from the outlaw role, I also wish for a gunslinger role, where you can become a you know, a gunslinger, challenge people to a duel and you can win money and such. It may sound ridiculous but it seems like a decent idea, for me anyways. But what else should be included?
