How could you absorb chakra from a Shadow? i don't really see that happening... it would be weird...
And about Shino, yea he controls his bugs with Chakra but he doesn't have to use so many bugs at once, he could send them one by one to like tear up kisame or Samehada from the inside? maybe it could happen.
And Naruto? Well in SM i most surely think that Samehada would turn to stone, in which case it would be a very useless sword (not even a sword but more like a blunt weapon) And without it just like you said Kisame is just your ordinary Ninja...
