Wouldn't madara's susanoo be as strong if not stronger than bijuu susanoo? Can kaguya even destroy that with vaccum fists?
Madara would have to release the Bijuu (stop being Juubi Jin) and then sealing it directly into his PS for his PS to be superior to Sasuke's Bijuu PS.
Note that what Sasuke did wasn't become a Jinchuuriki but rather store all that power into his PS in place of the Gedo Statue in addition to it being powered by Rikudo chakra. Kinda like his PS became the Jinchuuriki instead of Sasuke.
Madara's PS would be powered by Rikudo chakra due to the Juubi just like Sasuke's PS was powered by Rikudo chakra thanks to Hagoromo since Hagoromo inherited his chakra directly from Kaguya who just so happens to be the Juubi (a part of it anyway but same kind of chakra either way).
IMO anyway since even Kurama noted that only Hagoromo was capable of doing something on that level. Not Madara. Unless that wasn't Viz translation.
