With the Rinnegan, Madara should have access to Human and Hell Realms' abilities. He could remove Hashirama's soul (assuming that the abilities of Rikudou Sennin override the binding effect of Edo Tensei like the Sword of Totsuka does) or have it sealed via the King of Hell. So that gives Madara the necessary tools to succeed. On the other hand, Hashirama has not shown any sealing techniques.
