Question about Dottore's mission and possible aftermath

What if Dottore's death is part of his plan? Cause he talks about space, time, life and death. Also where does the dead go? Back to Irminsul? So now he died as a god and absorbed by the Irminsul, will this start a Sumeru AQ where he actually burns Irminsul from inside? Also what do you think his mission from tsaritsa? Im leaning towards getting the authority from the moon goddess, then columbina said that she left the authority of the moons in the frost moon. Will columbina trade this or her life for something else like nahida did? Curious if anyone have idea or solid theories, I'm all ears.
