Well, I doubt it would have changed much. It could've had the opposite effect in fact. Koto is powerful and all, but once the target is aware they are under it's effects, they are seemingly able to dispel it. A reference to this is Mifune, once he was aware of Koto being used, he realized his actions.

What would have likely happened? Naruto and Sasuke would have fought, Sasuke activates EMS, crow pops out with Shisui's eye. Sasuke wouldn't know the ability but he would expect some sort of visual jutsu arising from the MS. Koto would land and it would compel Sasuke to "protect the leaf".

However, Sasuke would still try to deduce the mechanics of the MS that just appeared. He would eventually concluded that genjutsu was used. Thus, the effects of koto would be negated. Once this happens, it would further enrage Sasuke as it is another action that Konoha "forced" Itachi to do for the sake of the village.

Enter a more deranged version of Sasuke.
