Or maybe it is all total bullshit and the Mandalorian clan is indeed just a cult, but that’s the fun of it all. That’s how most of the galaxy perceives Mandalorians in the first place.

A thought that crossed my mind: The normal Mandos have the belief in the darksaber, the CotW the belief in the Mythosaur, both indicating the true leader of Mandalore.
The darksaber gets destroyed, but Bo Katan still is accepted as a leader. Not knowing your exact plans, maybe it is possible to do something with this thematic connection to resolve the darksaber thing which was kinda brushed aside in the show?

You already established that belief in the Mythosaur is belief in Mandalore. So what if the normal Mandos kinda also make a step towards the beliefs of the CotW. Mandalore has been retaken despite the darksaber being destroyed, so apparently (in their eyes at least), it was not the signifier they thought it was, so they accept the Mythosaur as a representation of Mandalore and the justification for Bo Katans claim to leadership.

This way each side would move a little bit towards the other. The CotW are less dogmatic about the helmet thing and the normal Mandos take on a core bit of belief of the CotW, with both groups now having a newly established common ground they can build upon, giving the Mandalorians as a people some nice growth.

Hope this was not too convoluted.
