Considering the Last Dragonborn is pretty close to being a Living God himself, then examining the nature of the Black Books, the Last Dragonborn can still be written to evade Hermaeus Mora. After all, do the Daedric Prince of Fate really want to pick a fight with the Chief Deity of Time, Akatosh because the Dragonborn is literately a piece of him... plus possibly a Shezzarine as well who got empowered by reading the black books (Knowledge Hermaeus gathered)

The Last Dragonborn's fate can be up in the air. Meaning this is one wild card.

Then there is someone else, potentially just as powerful as the Last Dragonborn and possibly grown even more powerful during this time he supposedly visited Akavir... yes, I am talking about Nerevar, hero of Morrowind who pretty much became immortal. He is also a wild card that can be written back to the next game with the LDB.

Another factor. Basing off common practices by Empires, Kingdoms and countries in general will have at least like 9000 backup plans (legit candidates related to the Emperors in blood) I don't believe that Alessia, Reman and Septim bloodlines are completely wiped out. Take Skyrim for example, you have one who is related to the Septim bloodlines but the Elder Council are simply not actively seeking them out because it does benefit them more politically not to seek out and put a higher power to lord over them / keep them from doing whatever they pleases.

That is probably why the Elder Council wants Titus Mede II killed anyways: Conflict of interests. Such is the ways of politics
