Hagoromo possessed Yin/Yang seals and Gedo statue. And his power was still above JJ Madara's so I don't understand how you see him losing.
The only form of Hagoromo that possesses the Gedo Mazo is a version of him that was stated to be weakened and half dead just like Obito was after the Biju were extracted from him. Not like it matters though since the Gedo Mazo isn't strong enough to be a factor in this match.
Hagoromo is stronger than Madara, but Kaguya is stronger than Hagoromo and the team that beat her isn't even close to this one, so I'm not sure what you're arguing here.
Giant CT would seal all of them instantly like it did Kaguya.
What giant CT are you referring to? Moon level CT requires the Yin/Yang seals and he has to touch the target with both seals in order to activate it.
There's absolutely no reason why one person being turned into a CT core would magically make the entire team get sucked in and using Six Paths CT on one of the shinobi in this thread would be a waste anyway.
