Yeah, but Hal's off planet right now, dealing with the blackest night or the lantern wars or some such rot.
Only other guy I can think of is Green Arrows, and from what I've heard of his recent comics....no, just no.
Its pretty sad when the only reason they can't round out the JLA with a classic era member is because all the original members are either dead from bad crossovers, wrapped up in bad crossover, or in the hands of incompetent writers.
...And Wonder Woman, I guess we could use her. But I think there's some unwritten rule that male characters have to outnumber female characters 3 to 2 on a hero team. (Unless its the Runaways, who are awesome).
