While I would love to see a sequel to "Green Lantern" (and I'm still hoping they make one), I think the safest bet for Warner Bros. and DC Comics would be to plug the character of Green Lantern into a "Justice League" movie. Warner Bros. could have Ryan Reynolds reprise his role from the "Green Lantern" without people holding the movie against him (because even if people hated "Green Lantern", they will likely still see "Justice League" because of Superman and/or Batman). This would provide the perfect project for the character of Green Lantern to redeem himself. Christian Bale will likely be quitting the Batman franchise after "The Dark Knight Rises" so a "Justice League" movie would also be a great project to launch a new actor as Batman without waiting five to ten years on a reboot.
Assuming Christopher Nolan has a change of heart, it would be a good idea to also use Henry Cavill as Superman in a "Justice League" movie. If Nolan doesn't want his Batman or Superman in a connected universe, bring back Brandon Routh to co-star with Ryan Reynolds. Routh wasn't a bad Superman and he had his fans. Plus, the upcoming "Man of Steel" could serve as a reboot starring Henry Cavill while a "Justice League" movie could serve as a sequel to both "Green Lantern" and "Superman Returns". If "Justice League" does well, Warner Bros. could then move ahead with a sequel to "Green Lantern" as well as spin-off films starring Wonder Woman, Batman, Aquaman and The Flash. Warner Bros. had a similar plan a few years ago with "Justice League: Mortal". The problem with that film was mainly the cast. I doubt most people would mind seeing Henry Cavill or Brandon Routh as Superman and Ryan Reynolds as Green Lantern (and I know people would love it if Christian Bale played Batman again). (Personally, I would also love to see Jessica Biel as Wonder Woman, Matthew Fox, Jensen Ackles or Ryan Phillippe as The Flash and Armie Hammer as Aquaman).
Sadly, I doubt Warner Bros. and DC Comics will follow this advice, and maybe it's best if they didn't, but I do think the studio is missing out on a possible gold mind. It's working pretty well for Marvel Studios so far to have a connected universe. Movies based on DC Comics should take a slight clue from Marvel in that respect. There is money to be made from connected characters worlds.
According to The Hollywood Reporter, a Warner Bros. spokesman said that a decision on making "Green Lantern 2" has not been reached. With the low box office total for "Green Lantern" so far, the fate of the sequel isn't looking good. Still, I can only hope.
