It should definitely affect Madara. But to beat him is another matter. Frankly both Madara and Ichigo need feats. All we know is that Ichigo is at his strongest ever and supposedly several times stronger than Dangai and that Madara superscedes Juubito in power. Renji is the only one with decent feats and strong as he is, he's fairly irrelevant. He should be kage+ level but that isn't much to Madara.
