I don't quite follow. Eternal Mangekyo requires an eye transplant. That's generally accepted fact. Itachi transplanted his eyes into Sasuke's eye sockets, but since he was dead, he didn't need to take Sasuke's eyes.

Kakashi always had an Eternal Mangekyo because his eye was transplanted from Obito.

Izuna transplanted his eyes into Madara when Madara's vision started to fade. Why Madara didn't transplant his eyes into Izuna, I don't know, but again, whatever.
