I mean to bring all four Hokages back and give Orochimaru his powers back in order to finally learn everything. He can of course learn literally everything since he has the whole Konoha history in front of him.
Maybe he could even use some of them (or all of them who knows).
But...but...this move is just too risky.
1) One of them knows too much about Edo Tensei. He might even be able to break Edo Tensei and be a Madara-like problem for Sasuke.
2) That same guy might be able to free the others too and then Sasuke will know his truth but would be reduced to a mere spectator for the remaining of the series.
3) Even if the Hokages play fair (or get trolled by Kishimoto) there is still Orochimaru. Ok there was a slight change of heart there when he talked about Hebi and Taka but...that dude is insane and very strong.
