Excalibur/SWORD by Al Ewing would be EPIC. And he would definitely be able to handle both sci-fi and fantasy. Plus imagine him writing Betsy, Rogue, and Gambit.
I fella can dream. It would probably have to be bi weekly and have two fast artist.
And if they were to combine books they literally just have to change the titles and make the rotating artist schedule work and we'd get bi weeklys.
Doesn't DC do this sometimes with titles. Also the Spider Man office did it as well right?
