McFarlane revealed in 2015 that he and Capullo were working on a Batman/Spawn crossover, which never actually materialized. It's unclear if this new project is related to that one, though it's unlikely.

Capullo is arguably most famous for his work with Scott Snyder on Batman. However, the artist has worked in the industry for decades and earned critical acclaim for his work on various titles, including McFarlane's own Spawn. Capullo's comic The Creech was published through Image Comics in 2002. In addition to being part of the team that founded Image Comics, McFarlane is famous for creating Spawn and designing Venom.
