I got to thinking about this the other day and how the Justice League just does not feel right with J'onn not being on the team. They showed at some point in the Nu52 he was on the team but was spying on them or something and created the bad blood between him and the League since then. I am wondering now with Superman being the older version who had great relationship with J'onn in his reality if they could use that as a stepping off point to get J'onn back in the League like he should be. It would be a logical way to undue a bad idea they came up with in the Nu52 in my eyes.
Anyone else think this might be a good idea?
