I think absorbing Tsukuyomi is kind of overreaching it. Genjutsu pretty much happens instantly. There's really no time to activate the Preta Path, and as it's been clearly shown, it doesn't activate automatically. But that said, I doubt Obito would even look in his eyes to begin with. Itachi's only real shot is if he can stunlock him with a Genjutsu. Obito hasn't been shown to be immune to Genjutsu, so the most he can do is break out. But even then, Obito could probably break free fast enough to Kamui before Itachi can capitalize, since he has shown tremendous reserves, Genjutsu capabilities (controlling a Kage caliber shinobi for years), and overall abilities.
