As long as the characters are new, I'd OK with it. Trying to recreate the originals as different races or genders wouldn't really work. It would be nice if the new show were set in the same continuity as the original show and had the surviving members of the original cast show up as their original characters.
I'm waiting for new news on this but hate the idea of a female A-Team. You can't keep the spirit of the show that way and wth is so wrong with keeping it four men? I could see the female reporter angle working if they did it right but the feminist movement will survive if there's a show without a main character woman in it. Really.
