Lorkhan/Akatosh - Shezarrine/Dragonborn Theory

[EmporerLobster]

Hi everyone, just wanted to see people’s thoughts on one of my theories made up of two other topics mashed together.

I have seen it discussed that the being whom spoke to Slave Queen Alessia was actually Lorkhan.
I have also seen a lot of discussion that the Dragonborn maybe be a Shezarine.

With this in mind, could other actions in history taken by Akatosh actually be Lorkhan?

For example, if Alduin was created by Akatosh could the last Dragonborn be Lorkhan’s response to prevent the destruction/enslavement of Tamriel and sovngarde?

And is there any other instances of Akatosh contradictions that could just be Lorkhan pretending to be him?

And is there other times when gods/daedric lords pretended to be other deities?
