False.
I don't know where everyone is getting the idea that MS jutsus take away so much chakra. Itachi spammed them as he was dying of disease and after he had already fought part of a battle with a fully healthy Sasuke.
So Itachi + fatal disease +half a battle can spam Amaterasu, Tsukuyomi and Susanoo, then I'm sure Sasuke can as Itachi was said to have average chakra levels.
Anyway my point is MS jutsus don't take all that much chakra. It is a myth, the only real downside is the deterioration of vision. And we saw where that got Sasuke. He went blind in weeks whereas Itachi had the MS for like a decade without going blind. (manga facts)
Raiton armor takes a huge amount of chakra. Only people like the raikages, Jiraiya, Kisame, Nagato, Naruto or jinchurikki could hope to do it.
