The sword would be the least of Itachi's worries.* Kisame has created multiple sharks before in his shark jutsu that seem to act on their own.* Itachi's in the clear if he uses the sharingan. But what i'm saying is*the tsukoyomi is a genjutsu technique enabled by the mangekyo sharingan.* Even though it's using the sharingan, genjutsu is a focused technique.* Leaving openings from behind.* Even with the sharingan, Itachi would have to switch between both. I doubt that technique would be used.
