I don't think it'd change anything, at least if Danzo wouldn't have managed to affect Obito with KT (since Obito was the main villain back then). Danzo already got one or several mortal wounds which couldn't be undone with Izanagi because they were inflicted before it could be activated and thus would stay anyway. Sasuke being affected by KT also doesn't matter, Obito would've quickly noticed that and inform Sasuke about him under genjutsu influence, which is enough for Sasuke to realise it and make this choice useless.
