Its just absurd to think that kakashi would give naruto the sharingan. First of all, surgery isnt training. Next, receiving the eye isnt something only naruto can do, and the sharingan itself only eats insane amounts of chakra if it is already mangekyou. Lastly, even having the sharingan, there is no way naruto will pass, or even get near kakashis level (even without the sharingan).
