How about a quest explaining who Konahrik is, perhapes we could get to use the wooden mask to travel back in time, in a way, to discover what Konahrik did to become the leader of the dragon preists. Konahrik would be ressurected and he would gather all of those still loyal to the dragons and mass a undead army as well as dragons who still belive that dragons should rule over man and start another dragon war, only this time you get to experience one as you help holds fend off against a army of th'um weilding draugr, powerful dragon preists, and deadly dragons. There would be a few parts where you would mount Odahviing and battle dragons in the air although of course these dragons would need to be weaker than your typical dragon because it would tedious to do a air battle with a dragon because of their large pool of health. Perhapes another fight in Sovengarde between the dragon cult and the heroes of Sovngarde, that would be pretty awesome.
