I doubt if anyone outside the 1st Sage's bloodline could contain something as powerful and destructive as the 9 tails. The Senju had strong bodies like the 1st Sage, and I imagine that it was the same genetics in the 1st Hokages chakra that allowed him to do wood, that allowed him power over a Buuji. Im also assuming that since Yamato made the statement about Naruto's own chakra being special because it had power over the 9 tails, Naruto may have unique chakra power over Buuji.
Inside Konoha, I dont really see a reason for them to have needed a jinjuriki. They had Hyuuga, Uchiha, and Senju. Those 3 clans alone, and their genetic potential could put up a match against any Buuji that any other nation could control and send their way. Im guessing Raikage or the 3rd Raikage got cocky once Killa B was old and strong enough to finally control the 8 tails and that is why Konoha was threatened with war and that's why Sarutobi gave into their demands, but until then, I doubt if Konoha really had any serious threat against other Buuji and a need for their own.
Plus, trying to put the 9 tails in somebody would be extremely dangerous for the village as seen by the 8 tails in the Cloud village in the past. Konoha has not had the type of rulers to take such risks and reduce a child to an ultimate weapon without a serious need, and that didnt seem to come about until Minato saw it as the only way to save Konoha and help his son and Konoha defeat the "guy in the mask" in the future.
Ok yea the son of the RS could have been a host .. but the fact remains that was generations before Hashirama.. that being said after he passed away and there was no-one powerful enough to control the 9 tails.. (as currently it is unknown whether or not Tobirama could use the necklace and control the Fox) it must have been placed in a sealing pot or a jinchuriki because if it had been allowed to roam free and was an "act of nature" then any other village with strong enough shinobi could come along and collect it just like the third Raikage and the Kuomo nin did to the 8 tails when it got loose.
If the Uchiha could tame it then that means they would have had access to it .. if they had access to it then Madara would have just taken it from whatever Uchiha had it in their possession as he was the most powerful.. id he could have had it back then he wouldn't need Itachi to get revenge on the clan.
That means that the Senju had the fox in some manner whether in a sealing pot or better yet a jinchuriki as it is the traditional form of containing a biju. The need for Konoha to have a Jinchuriki biju is to cement the shinobi might of the Leaf village . which means we have the strongest biju and the two most powerful clans of ninja ever the Uchiha and the Senju so you better not mess with us.
Kuomo wanted to get their hands on the Byakugan because it was a powerful kekaigenkai and it was a far better calculated risk than attempting to take away a biju that would have been heavily guarded or been able to destroy any ninja to come take it.. as seen in the latest issue it'd take a group of powerfl shinobi to take down a biju and a stealth mission of that caliber wouldn't go unnoticed by the leaf shinobi.. so the Lighting nin took a chance at getting what they could from the leaf.
