Since being intangible with kamui is limited to two minutes,Itachi would take that two minutes to hit his Tsukuyomi on him. Itachi's prowess with the technique has allowed him to alter the perception of time with ease within the genjutsu to make a few seconds seem like many days as a means to torture the target. This results in the victim suffering psychological trauma that incapacitates them for a considerable period of time. After Itachi used it on Kakashi Hatake in Part I, Kisame Hoshigaki was surprised that Kakashi's mind was still intact. Only Tsunade has been shown capable of curing this psychological damage. And Tsunade won't be there. The thing is that Tsukuyomi can only be broken with a sharingan and the same blood so it will be over for Menma. Furtheremore,f a victim is forced to experience a drastic passage of time in the fraction of a second Tsukuyomi is actually active, the stress on their mind would kill them, even if the genjutsu was a happy and peaceful one, such as when Itachi uses this technique to kill Izumi Uchiha by having her experience decades worth of time in a fraction of a second. This is definitely too much for Menma.
