They needed to seal him with Moon/Sun marks anyway, since he got the same full immortality Kaguya has. Kaguya regenerated her whole being from total obliteration, the ETSB.
It depends if Juuudara can no sell 9 Bijuu Rasenshuriken like Kaguya did.
Also curious thing here. 2 Rinnegan Juudara was able to dimensional travel from Kamui isolated dimension to Naruto Planet, something like Kinshiki when he dimensional jumped into Momoshiki's dying solar system.
Zetsu using obito took madara with him
Madara used Kakashi eye to get there, Zetsu brought him back once he got 2 rinnegans
Madara doesnt have dimension hopping without taking Obito/kakashi eye
