Waste of time.
Out of topic: about your sig, hey at least RS has actually done some meaningful things so far unlike amaterasu that hasn't even killed anybody yet, besides fodders.
Nope the only thing that can effect him is sage, like naruro,jiraiya,and i guess kabuto. But so far nothing else, and to answer your question, yeah no genjutsu isn't going to work on him.
I'm just saying i don't see that happening on obi.
