Any flesh from Madara's body would do for Hashirama to awaken the Rinnegan, the eyes are not necessary. Yeah that's the thing. If this was true, and assuming Hag and Hamura's descendants are "spread" similarly, then how come Toneri needs a Byakugan to awaken the Tenseigan? Granted he needed eyes, but are you saying that if he had eyes beforehand, he would've only needed the flesh of Hanabi?
