Itachi's eyes are compatible with Sasuke (because they are his sibling's eyes), so they are assimilated by him and essentially become his own eyes when transplantated. Otherwise the EMS cannot be created, since there's a necessity of the compatible eyes - compatible by genetics and by chakra. Naruto isn't Sasuke's sibling, so if he gets Sasuke's EMS, for example, it still would be a foreign material for his body and he must be accustomed with it, which is a lot harder for him cause he doesn't possess the special chakra of the Uchiha in the brain (the one which influences the eye nerve and awakens the Uchiha doujustu). Only thanks to this chakra and it's influence on sibling's transplanted MS, the EMS appearance is possible. Yeah, if evolved into the Rinnegan, the eyes become Naruto's own Rinnegan, but the point stands clear - doujutsu isn't his speciality, so his mastership of the Rinnegan, if not inferior to an Uchiha, would need a lot more time and training to perfect.

Edit: again nope, BZ specifically stated that the Uchiha clan was chosen by him as a main tool to achieve his goal. Otherwise he wouldn't be so fixed on them, tempting Indra, rewriting the Uchiha Stone Tablet and influencing Madara.
