"Lemire told the paper that it was all Dan DiDio, and it spins out of Forever Evil. “As a result of that, without spoiling any of that story, there will be major changes in the Justice Leagues, and in the spring, the current Justice League of America team goes through a dramatic change and some of the pieces that are left behind will evolve into this new Justice League Canada team” and that a new character would be “a real Canadian teenager. That’s what I’m really after with that” and that one of the characters would be Adam Strange.
But a Canadian Adam Strange." ` from http://www.bleedingcool.com/2013/08/...a-jeff-lemire/
Moke, what you listed sounds basically EXACTLY the lineup from JLA, which doesn't seem to fit with the "major changes in the Justice Leagues", or "some of the pieces that are left behind" that Jeff Lemire mentions in the quote.
