Could a mortal armed with the Thu'um have driven back the Daedric Princes  or the Tribunal? Absolutely not, though it might have been the fight of an age.

Could several Tongues have turned the war against the Aldmeri Dominion? Very likely. Even a single Dragonborn might have turned the tide. Tiber Septim was able to use the Thu'um to reshape the very face of Tamriel.

Much like the Dragons themselves, the Thu'um is a sort of immortal, semi-divine thing. I like how you put it best. I'd argue that several of the most talented Tongues could give the Daedra or Tribunal a good fight.
