Madara has no reason to come back to life, after knowing he was someone's tool and accepting the fact Hashirama's dream was stronger than his own.

Susanoo? Madara could use it after being revived despite having no eyes at the time.

His right eye probably regained its eyesight when he awakened the Rinnegan. Seeing how Edo Madara had the same Eternal Mangekyō Sharingan in both eyes, it sounds likely.
