I was thinking about something about Naruto's SM. Pa said that he couldn't merge with Naruto because the Nine-tails was rejecting him. If Naruto has gained control of the fox completly (meaning that both are one good terms with each other) could ma and pa merge with him then if the Nine-tails won't reject them? This doesn't have much to to with the question but it's near that topic (also technically Naruto still has one clone in the Toad village, he never had a chance to summon it unless the jutsu has been released already Idk if anybody picked up on that)
On topic I think both would end up dead.
