And how do you know the shockwave isn't chakra-based? This wiki states that the Tailed Beast uses its immense reserves of CHAKRA for the technique. I'm pretty sure it's chakra-based.

Also, Tenpenchii was only ever used by Ten-Tails. Having a fragment of all the Tailed Beasts' chakra probably isn't enough, I think it has to be the reformed Ten-Tails to perform it.
