Alright, so most of us would agree that Obito has Senju's DNA, confirmed by the right side of his body being smashed earlier in his life compare to now. In addition, he always get gooey with this white slime whenever a limb is cut off. This suggests that he probably has Zetsu power (whom was an experiment that has Hashi's DNA). To solidify my statement, the ability to use Izanagi means you need to possess the power of Uchiha and Senji, as shown in the battle of Tobi vs. Konan.
I'm not sure if a post like this has been posted or not yet but to make an attempt of a different post than others, how about this theory. Let's say the ability to use Izanagi isn't limited to those with Uchiha + Senji powers or maybe both of Obito's eyes (which Kakashi has one) are able to use Izanagi because the original owner of the Sharingan have unlocked Senji and Uchiha powers. What if Kakashi ended up killing Obito by using Izanagi? (Like how Tobi killed Konan) Wouldn't that be crazy! Or an interesting plot Kishi can use to troll us?! Haha.
Anyways, the theory is just a theory, I don't think this will happen but hey, would be crazy if it did. Imagine this, Kakashi ended the life of Obito by using the eye that Obito gave to Kakashi when Obito thought he was going to die.
