True but what you're doing is speculating to the extreme, although I do respect your point of view.
The SO6P had the rinnegan when he performed Izanagi(according to Obito) which clearly differs from the Izanagi Danzou and Obito used. Furthermore, Itachi used Izanami so why should you question his knowledge and what he said about Izanagi?
Itachi hardly learned a thing from Tobi, we KNOW this. It was just a ploy to provoke Sasuke and make him not trust Tobi. We saw in the flashback that Shisui was much more of an influence on Itachi than Tobi ever was. All he did was meet Itachi the night before the massacre.
