Sounds like a dumb awakening tbh, haha. I think awakening will strengthen his body further. Imagine Blackbeard switching off Luffy's DF, turning him into base without rubber durability and smashing him with a Gura Punch. And there is strong indication Blackbeard will eat a Zoan too, to boost his durability. Luffy will have no chance unless he is able to suppress his DFs.
