Imo no and he doesn't need it. I think him gaining a 3rd df likely a good zoan fits way better with bb than him gaining adcoc. If he does have it then oda going to need another gauntlet fight for luffy to beat him like with kaido. Bb doesn't need great haki since he has the 1 and only ability to eat more than 1 df. He bb has great haki and 2 great df how realistically does anyone beat him unless it's by wearing him down?
