As long as neither of the Winchesters dies, freeing Lucifer and Michael would be their best chance. They hinted Adam's return a lot last season (compared to every other season since season 5), and Michael may be able to help them find God (Isn't Michael God's eldest? Correct me if I'm wrong please).
