Wonder Woman by Greg Rucka: Wonder Woman #15 to 226, the Hiketeia graphic novel, and the Blackest Night mini.

StormWatch by Warren Ellis: Collecting Stormwatch #37 to 50, Vol 2 #1 to 11, and the WildCATS/Aliens one shot. Not going to happen anytime soon due to recent controversy, and even when that's resolved, it may not be released with a "By Warren Ellis" subtitle. So maybe StormWatch: Change or Die Omnibus instead. I'm also not sure what the status of the printing rights for the Aliens one shot is. I know Marvel has the Aliens licence now, but all the Alien stuff that Dark Horse co-published with DC and others is still available on Comixology so maybe there's some hope.

Superman by Jeph Loeb and Ed McGuinness: Collecting their run on the Superman series in the early 2000s, as well as related one shots and crossover issues.

Superman: Our Worlds at War: Collecting the full Worlds at War saga, including crossover issues, one shots, and tie ins. This is a slight cheat on the "done in one" rule, because it would be a sort of companion for the Jeph Loeb omni.
