None that I have heard of. The industry still thinks that the market will only buy the super-powered crowd and that a highly skilled human with a gun will not sell.
A few pages ago I tried to make the case for a revival of the Ringo Kid: multi-racial with all sorts of opportunity to face racism from both sides; with a family vibe (his father and blood brother always help him out)--a fascinating merger of both the loyal-family trope with the loner trope. And with the mix of the law hunting for him while, at the same time, a number of law officers treating him as a trusted aide--rather like Batman in the early days, or the later Green Hornet: officially wanted, but unofficially friends with the law officers. There is just so much that a decent writer could do with the Ringo Kid.
But nothing on the horizon that I have heard.
