I recently realized that some of my favorite D.C. characters are black - Black Lightning, Vixen, and John Stewart Green Lantern.
Do you think a team series featuring these three together would sell well enough to survive? Personally, I would love it!! They are very different characters with different points of view. Throwing them together could be fun. And having them at the forefront doesn't mean you exclude others from appearing, I'd just want to keep those three as the primary focus of the book.
