CLONES!!!
I'd probably cry... xd
That would be going too far.
O_O
Then Naruto could make 1000 kyuubi clones maybe...
LOLat that point not even plot no jutsu could stop him.
I actually don't see what would be the problem with that. He has already made over 1000 clones of himself. Now that he has complete control over the Kurama's chakra he could just do the same. Shadow clones are nothing more than go on deciding your own chakra in as many clones as you can. Obviously one has to take into account that the more you make the weaker they are as you'll be cutting your chakra in more and more equal parts. Ence why most keep clones to a minimum.
I meant Naruto being in Bijuu mode and making 1000 real Kyuubis as clones...
