Why would they move the it tho? Gyuki was perfectly fine with B. Hell we saw them together, during the epilogue.

EDIT: And it's worth noting that Naruto had the whiskers before Kurama was sealed inside him. Assuming the whiskers are tailed beast related (which I'm assuming they are, since they seem to react to Kurama's chakra like his eyes), it's possible they can just be passed down.

Now the tattoo of the horns on the other hand, I think that's just a thing B likes to have.
