Interesting idea, although Brucie hasn't been confirmed as a Black Lantern just yet, I believe so far we have Black Hand, Martian Manhunter and Firestorm. What I was thinking was that since Darkseid hit Bruce with his Omega Sanctuary, which means his soul is going through a series of dimensions, each more horrible then the last, that they might do a story arc where he has to get back, or become redeemed or something, kinda like the Green Lantern Rebirth with Hal Jordan coming back
