How would that happen? Edo is a body, with a soul sealed into it. This sealing kills the original soul as I assume only 1 soul can habitate a body at one time. If Naruto were to make the Edo "real" then you need to remember that the Edo's body isnt its own. So if revived, the seal would be broken, and the body would revert back to its original form. For example:
Random fodder is used as a sacrifice to Edo Summon Hashirama, Fodders body then transforms into Hashirama's body as part of the Jutsu. Naruto makes the Edo "real" broking the Jutsu. Hashirama is now alive and kicking but now that the seal is broken the body reverts back to the Random Fodder ninjas body. Now you can say "Why couldnt they make it to where the body doesnt revert back when made 'real'", if that was the case why make the edo in the first place, why not just use that Jutsu to make everyones body into Hashirama's and have an army of Hashirama.
