I can think of many ways to have an oc that has a Sharingan. But having an oc that is an Uchiha after the massacre is a different story. The Uchiha clan probably never would let an Uchiha mate with people outside the clan, and they all probably think badly of it anyway. Not to mention Itachi was very thorough with killing all except Sasuke, and I bet Hiruzen and Danzo made sure of it too. My minds a blank xD
