- What is Ninshuu? Once you understand that, you'll understand my point. Ninshuu is not an exchange of spiritual energy, but a chakra relay system. Naruto didn't share anything other than Bijuu chakra with others. This connected all of them together and they could see into eachother's thoughts. This is what Ninshuu is.
- I disagree with the rest. Without communication, the chakra can run out, as it happened.
Your posts are very long, man.

This link leads to the very manga scan that proves that ninshuu involved the connection of spiritual energy between two people to allow communication without words to take place (just as I said). It is not just sharing chakara with people like Naruto's cloaks.

This link leads to the scan that proves that Naruto did not use ninshuu to communicate with the bijuus, and that it was just due to his link with Kurama. Notice that Naruto didn't even know how he got to that room and Kurama had to explain it to him. That fact further proves that Naruto didn't use ninshuu.
As for the bijuu chakara thing, let me ask you this:
If portions of bijuu chakara run out (even if they manifest into a whole bijuu), then why didn't yang Kurama or yin Kurama not run out permanently? Is a half still not a portion? Also, why did Naruto not die at the end of valley of end 2 when Kurama's chakara ran out if your logic is correct? Shouldn't Naruto have died due to losing his bijuu (since according to your premise, once a portion is gone it stays gone)?
This next link I am about to post is proof of what I was saying about a person becoming the jinchuuriki of a bijuu if that bijuu's chakara within them manifests as a whole beast:

Notice a whole Kokuo inside of Naruto?
Another thing: Even if it had been ninshuu that Naruto used to talk to the bijuus, how on Earth would Gaiden Naruto establish the connection with the bijuus that is necessary for ninshuu when the bijuus are not even physically near him? He'd have to actually physically hunt the bijuus down and ask for more chakara. That would make your premise even less likely to be true.
Finally, do you understand now that in my original post I was actually agreeing with one thing that you said when I said that RSM was the form Naruto donned when he kicked Madara's gudoudama?
