So you the Dragonborn, knows how to make daedric armour, has access to crossbows that only the dawnguard uses, has
collected vast amount of dwemer [and other races] technology along with knowing where the aetherium forge is and has collected a vast
amount of unique artifacts like the staff of magnus and auriels bow.

Now if I wanted to defeat the Thalmor and I was the Dragonborn, I would certainly direct Ulfric and the nearest Stormcloaks to the Aetherium
Forge along with any mages at the Winterhold college, who have experience with the eye of magnus. How long has it taken for someone to
figure out how a centurion works? The dragonborn should really teach a load of people how to make daedric/stahlrim [ship a few skaal over to work it]
artifacts, while having the mages study auriels bow. Teach stormcloak soldiers how to thauum.

Aetherium spears while wearing stahlrim armour and become ethereal thauum for everyone!
