It is possible that the justice league add new members too, that they haven´t show yet. But Guy Gadner had done some jobs with Justice league before, one of them  was on episode 13 "Revelation" he fight against the plant of injustice league. The Green Laterns dont want him on League due to hisfor brash attitude and machismo. And trust me that Justice League have too many problems without him. He could still has his role as ally of Justice League.
