What if Shazam becomes the 7th Justice League member?

Given that his movie is supposed to come out in 2019 before a possible JL sequel, I think it'd make sense for him to be recruited as the League's newest member. While it would be disappointing to not have a Green Lantern as part of the core team, it wouldn't be surprising, given that WB is still trying to pretend that the 2011 movie never happened.

So what would you guys think?
