In 2015, DC Comics announced Darrow as the artist for the supplemental mini-comic to the third issue of Frank Miller and Brian Azzarello's "", as well as the variant covers for issues 3 and 4, though none of his contributions were ultimately realized. Meanwhile, Dark Horse issued a press release announcing the first English-language collection of the "Bourbon Thret" strips, to be partially re-colored by Dave Stewart. Since then, Dark Horse has re-released "Hard Boiled" and "The Big Guy and Risty the Boy Robot" with new coloring by Stewart as well as the entirety of "Shaolin Cowboy" in a uniform format. As of 2019, the "Bourbon Thret" collection still hasn't been released.
