I'm sure it's possible to do something given enough time, but it's unnecessary. Remember, Naruto is the only known Jinchuriki whose seal was made to naturally feed minute bits of his demon's chakra into his system over time. Other Jinchuriki have to tap into it, the beast cannot just force the chakra in at whim. So I think controlling Yagura would have been enough, the Sanbi was less a factor. Ch 502, pg 8. Obito took control of Kurama then released it.

Naruto didn't know about that benefit of being a perfect Jinchuriki, we know for a fact that Naruto is basing this on what happened to Kakashi and Sasuke. Heck, Sasuke broke out of Tsukuyomi as well and Naruto didn't mention it because Naruto didn't know about that. Then Bee would have said "im a perfect Jinchuriki, Genjutsu doesnt work on me

Going by 413, Jinchuriki cannot instantly break Genjutsu. Bee still fell under it and was temporarily outcold. It was a very short period of time but Tsukuyomi effects are basically instant in real time.
