At the bold part, nice and all however that isnt what i meant. Ill use your example against you.
Lets say a bottle is 1L. The bottle was filled with water, but it run out. Instead of refilling the bottle with water, you fill it with alcohol. Which bottle gets you drunk?. I believe we can firmly say the bottle of alcohol, because the substance in the refilled bottle is completely different to water.
Ill explain further.
By kurama saying he will replenish kakashi's chakra in the previous chapter i dont think he means he would somehow make them rapidly regain their OWN chakra, but rather he would give them HIS chakra therefore replenishing their reserves. Kurama is filling their reserves with HIS chakra. Its just like how sasuke was running out of chakra at the kage summit and zetsu absorbed chakra. Zetsu didnt have the ability to rapidly allow sasuke to replenish his own chakra, but rather he replenished sasuke's chakra with the chakra he has absorbed. In other words you can say, Kakashi/Gai are running on kurama's chakra.
To put it simple, kakashi's reserves is water and kurama's is the alcohol. Whether kurama's chakra that kakashi is running on atm affects this is possible. Naruto in part 1 couldnt use the kuchiyose jutsu or should i say he could, but wasnt able to summon a big even toad and instead summoned tadpoles. With kurama's chakra however he summons the boss toad gamabunta.
Second is yamato's mokuton which he used with his own chakra. When it came close to naruto's yang energy that the fox's produce's it grew tree's. Its very possible that something similar is happening/has already happened
@the bolded part,
nice try, but try again.
@naruto's example,
(i don't remember the manga page but )
naruto have kurama in him, and when he got access to kurama's chakra, he got a chakra boost, which definitely helped in summoning gamabunta. Also At that time, we didn't even knew much about kyuubi , so showing something like that would not make sense at all.
It just represents that naruto gets extra chakra from kyuubi which makes him to do impossible things.
And regarding yamato's mokuton,
NO, it is just to show that Kyuubi's chakra have very much life force, so much that it can even make the zetsu grow into trees.
it represents connection to sage's body.
BUT , i don't completely disagree , your theory might be true, since senju DNA = sage's body = life force and kyuubi's chakra also shows life force, it might be true that kyuubi's chakra work as senju dna.
Also to further support your theory, naruto in one tail mode did one-handed rasengan, which he cannot do now.

BUT IT DOESN'T MEAN THAT, kakashi can't warp a bijju, Remember, the time, when kakashi was goign to kamui the gedo mazo itself, it didn't happen , but it would have happened if obito didn't cancel it.
And the fact that obito interfered , means it would have succeeded. Also we could see that kakashi created a big ass kamui gate, so it means he can create a big kamui gate, rest of it is done by kamui itself.
So for now, kakashi CAN warp a bijju.
