I wouldn't mind a turn, but I want them to stay a team. If they turn, here's what I'd like to see:
Kofi and Big E defend the titles, and are out dancing and clowning; when X. (not Xavier) Woods walks down the ramp. He tells Kofi & Big E to stop dancing because while they were having fun, he was at home watching the news. X tells them that "brothers who look like us are being hunted, and they got us out here shucking and jiving". X reminds Kofi and Big E that when he first approached them years ago, he said that they needed to TAKE what was theirs, and that now is the time to make it happen. He tells them that they may have the straps, but they deserve power. Black power. He goes on to say that there's no more New Day, because it's Now Our Day (N.O.D.). X becomes the manager (he could wrestle occasionally once he heals), and N.O.D. adds a couple more Black singles wrestlers to become a dominant unit.
As a bonus, here's their original formation.
