Either you stole my idea about the dragon army, or made it up yourself. :D Anyway, to gain the blades allegiance, you need to slay Paarthurnaxx. He and the greybeards are the only ones alive capable of TEACHING the Thu'um. As a dragonborn, I doubt you'd have much understanding for how the Thu'um works, and even if you didn't slay Paarthurnaxx, the greybeards would not teach the Thu'um to people of war. Ergo: Teaching the thu'um to the blades is... close to impossible. Good luck anyway!
