i am not talking about Edo Tensei, but something similar to Rinne Tensei but without sacrifice. Orochimaru stated he created a superior cloning technique with actual REAL CLONES not just ones that go poof when you hurt them but real living clones, so what would happen if he cloned say the Hiruzen and then used a revised Edo tensei to summon hiruzens soul and then bound it to the clone. this means he has the potential to revive the dead at full power in their prime and one that has a new lease on life
