That is not how EMS works. You keep the same techniques you had, you don't get new techniques on top of it. And there are many valid reasons to believe he does not have Tsukuyomi. For one, his genjutsu has never been called by that name. Second, it does not have the properties that makes Tsukuyomi a Tsukuyomi. Finally, he has what appears to be an MS technique in his right eye, Enton. I never heard of one eye having more that one MS technique except in the case of Susano'o which uses both eyes. These don't rule out the possibility of him having it, it just makes it extremely unlikely.
