Only one name comes to mind: Snapper Carr.
I'd like to see a leaderless League. Each member can have thier own area of expertise (Bats has urban crime, GL has spacey stuffs, Superman has Supervillians, etc), and can take point based on whatever particular threat they are facing at a given time.
i hate people who have clever signatures
The league doesn't really need an official "leader" as they are all capable of the job. Aquaman and Wonder Woman have experience leading actual armies, Hal has military training and is a high ranking member of the GL Corps., Superman and Flash are both highly intelligent and capable fighters. Cyborg as the youngest member is probably the only one who wouldn't be considered just because of his inexperience. In this continuity he hasn't lead the Titans. Give him a few years and he'd be more than capable. He could just download "The Art of War" or some other military guide straight to his brain.
Batman is going to bark orders out regardless of who is officially I charge. So just let him play leader. Plus he doesn't like taking orders from others. I loved the scene in JLA vs Avengers where even after Batman has said that Captain America is the best choice to lead the attack, he still ignores any orders and goes off to do his own thing.
Yeah you're a great leader of men...but I'm Batman.

BATMAN because hes GODAM BATMAN
Batman because he himself has Raised Leaders. I mean The Dude has the Best track Record ever of making Zeroes into Heroes under his Guidance. Damn near every person that comes out from under his training Is able to Rally Men and women Behind them in times of Crisis.
Batman would probably be an "ends justifies the means" kind of leader.
Aquaman would give preferential treatment to Atlantis.
At least with Superman you get an impartial alien farmboy.
