If i remember correctly, Hashirama and Tobirama had their appearances slightly adjusted to better fit their original selves (Hiruzen v Orochimaru). Seems to me that the Edo Tensei can simply change the appearance of that which is called from the Impure World, to fit whatever the user wants. (or to fit an earlier stage of their lives)

I don't see how this affects their power exactly. I even wonder whether Madara awoke his Rinnegan as an Edo Tensei, because the statements regarding Madara simply don't add up (According to Hagoromo, his transmigration was over). Seems to me that it was simply a cosmetic alteration. It's not clear how the Rinnegan plays into this, but then again it's not clear how he had EMS in this form either. Perhaps Kabuto also gave him some eyes?

Well, both Nagato and Itachi were revived with eyes, despite them not possessing them anymore. So Madara having Rinnegan isn`t an exclusion here.
