I thought that was what the cosmic Justice League with Darkseid on it was for.If they do that then they definitely need to give Guy and Simon a GLC book. I don't know why they haven't announced one yet when the storyline writes itself.
They need Lanterns to police that sector of planets they released in No Justice, to protect them from both interplanetary conflicts and the threats from the source wall. And it would tie in perfectly to Justice League because that was very thing Sinestro warned them about.
