The recent "Wildstorm" revamp comic by Warren Ellis had a really diverse cast. There was a "Michael Cray" spin off but I didn't think it was that good. There were "Names" and "Frostbite" starring black women from the Vertigo line over the last couple of years. "American Carnage" coming out right now ( although the art could be better). "House of Whispers" from the Sandman Line starred a black woman, it's started out interesting but began to meander after awhile.
I only read a couple of issues but there was a campy spy romp called "Knockout" that starred a WoC and her gay male sidekick.
A really good comic for LGBT representation was "Enigma" but I'm not sure if it's in print right now.
