It wouldn't have mattered, Kabuto re-awakened the Rinnegan in Madara's Edo body by implanting a Hashirama face made from Hashirama's cells onto the Edo Tensei. That Madara was from his EMS days shown by his age, clothing and all, and yet it re-awakened his Rinnegan showing that once a reincarnate always a reincarnated. Kabuto must have found the location of Madara's clone body that Madara left in the tomb Tobirama made in Konoha too while Madara's spirit was of him when he actually died of old Age.
