By sealing another tailed beast in him? Good luck finding some monster wishing to help someone who thought of them as pets. The Demonic Statue was just sealed in the moon, and it better stay there forever. The technique Chiyo used to revive Gaara is unusable because it was deemed a kinjutsu and only the old granny knew how to use it. Rinne Tensei? Only Sasuke would seemingly be able to use it, but no way he'd ever use it to revive Madara.

You don't need a full tailed beast to survive. Just some of its chakra. Look at Killer Bee and Hagoromo should be able to perform Rinnegan Tensei.
