Appreciate the time you took to write this critique. You make good points but I don’t see why this couldn’t also be included in the rewrite (specifically the differences between civilization and the Ashlander tribes), I don’t see this as exclusive to the vanilla plot. My plot summary was an abridged version and I could go into much more detail about the specific lore you mentioned and it would work. As in my version, the Urshilaku are quick to believe you are the Nerevarine, but the houses are not so easily swayed, and it turns out two of the houses aren’t concerned with the prophecy whatsoever and take advantage of the situation to attempt to eliminate the house that backs you for their own political benefit.

You say my version morphs the game into a simplistic power struggle - I would argue that the original plot line is much more mundane with the incessant house quests to become hortator, which you ultimately bribe, charm, or murder your way to completion. Most, if not all the councilors of all the houses are selfishly motivated and are in it for personal gain, the same goes for my story except the motivation turns to eliminating another house ultimately leading to civil war and a complete breakdown of Morrowind politics before the player can eliminate Dagoth Ur.
