So, JLU is - at least as far we now know - in a little bit of a limbo right now. No set creative team, no set creative direction, part of a franchise which already has 3 JL books, each with a specific mandate (Future Justice League, Universe-tied Justice League, Continuity-Lite Justice League). All the big characters are, more or less, taken (in fact, taken twice).
So, while we wait for the new team to be announced, let's make our own.
You have free reign to put together any configuration of a team you'd like. You can choose your characters, your mandate (cosmic justice league, street-level Justice League, etc), your artist and, if you like, a writer. Or you can write it yourself.
Only rule is that you have to use, say, one character from the Lemire run, for the sake of consistency. Any one will do.
Go forth!
