what i am saying is, Orochimaru could clone people like itachi, Nagato, Deidara Haku, Hiruzen, Jiraiya etc etc then using a summoning technique summon the spirit of the individual being cloned back to the impure world and binding them to a clone body. remember ultimately Edo Tensei is a summoning technique. so what i am saying is Orochimaru could clone a bunch of powerful shinobi then using a summoning technique he could revive the dead in a clone of them.

also Kabuto said that he nearly perfected it, thats why they were near there original strength but not at their original strength.
