I really don't think this fits into the whole soushi kg.

reasons:
1. The soushi bloodline's whole basis is around a sort of symbiotic relationship since the second twin needs the first one's body to survive.
2. Without some sort of fuinjutsu I can't imagine anything biological being being able to fuse with a weapon unless the weapon is itself biological like samehada (see kisame/samehada fusion) or it has some sort of special abillity.
3. I dont think putting a human in a sword would make it stronger unless it constantly drained chakra from them and used it and in great amounts.

Verdict: 1.2 deny
