I think it’s time Stewart got a chance headlining a book. Mark Russel has pitched a 12 issues series of John going planet to planet each issue solving problems with a co-lead GL who would be his romantic interest. I would like to see that, basically John getting his own “The Green Lantern” treatment.
For Hal I would give him a turn on the Justice League with the rest and let that be where he shows up. Actually I wouldn’t mind seeing Hal and Jessica being on the JL, since I think they could have an interesting dynamic.
Finally I’d have a GLC book with Guy, Kyle, and Simon. This would be your standard fare cosmic adventures, with Simon as the audience standin who could be filled in on the different Lantern Corps if any of them show up.
Yeah the fall off post Johns has been intense, but part of that is I don’t know if DC really has anyone with a strong pitch on where to go with the Lanterns besides Morrison. Sales might also play a factor, the Rebirth books sold on but not great.
To be fair, only Peter and Miles really sell well these days, and Spider-Man is on a whole ‘nother tier compared to GL, but it’s long past time for John Stewart to get another shot.
