[The Darklord]

I have always had a soft spot for well made/written westerns, things like unforgiven, the missing etc if you have seen the films.  Does anyone think it would be possible or worthwhile to try and run one?  Sure there would be issues about gunplay etc but it could be fun and its a setting that we havent ever really explored before (though of course some themes are pretty common)  I'm really looking for opinions and enthusiasm before I do any serious imagineering on it.
