Well, if she somehow lit the Dragonfires and proved she had the Septim blood, and if the Medes stepped aside to let her rule (say Titus II's son marries her or something), I don't think it would change much in the Empire.

If she or her mother appeared right after the Oblivion Crisis it may have held the Empire together, but by now it wouldn't help much. She'd have to reconquer or politic it all back together.
