IF someone eats it, I want Coby or Sabo(assuming if he someone lived being shot by a bazooka) to eat it. If not them, some new big bad guy that will expand for another saga or something. I doubt the 2nd one will happen but Luffy can not eat it. He will die. Only Blackbeard was able to by some means we have no clue how. It most likely is his devil fruit that is able to do it. Since Luffy does not have the yami yami no mi, he can not eat it. Assuming anything else like, his body is rubber so he can or, they both have the D in them so that could be why, is non factual and illogical.
