He doesn't need Jubis body,he needs JUbis chakra. Only Kyyubis chakra is sealed within Naruto as it was mentioned by Jiraya.
To become a JInchuuriki you basically need to have Bijuu's chakra sealed inside...
What Madara wants is to revive JUbi in order to become it's JInchuriki ( by collectig all the 9 beasts) and then place a Tsykuomi on the Moon with the help of JUbis power. Because Jubis chakra was devided into 9 :0
Moon is not visible from all parts of the world simountaniousy, moreover, there are moon sets and moon dawns which are mentioned in newspapers everyday
But Tsykuomi has a long lasting effect, doesn't it?
So basically all people will get affected.. and only those with strong eyes and chakras who are able to see through genjutsu will be able to resist Tykuomi.. but it won't matter as nobody would have the power to replace Tsykuomi from the Moon. Madara's plan looks quite good.
Aother thing is that this plot twist is unacceptable.. but that's another story
