We know that Orochimaru has thousands of Forbidden jutsu but he doesn't show them. We know that Naruto, Sasuke, Obito, Madara, Kakashi, Hashirama, Tobirama all have mastery with five natures, but none of them of showed using all five of them once.

Izanagi is no exception to that, if Kakashi could use Kamui, then it stands to no doubt he can use Izanagi with it, if he knows how to, unless Izanagi needs Hashi cells for non Uchiha users.

The difference is the skills you're listing have been stated and haven't been debunked. While Izuna or Shisui or Fuguku all haven't been stated to be Susanoo users.
