The Thalmor are assuming that since they're devolved decsendents of Aedric Spirits, then they should be able to inherit their ancestors' positions. Perhaps since the elves also ironically owe their existence to Lorkhan's trick (otherwise the elves would have never been produced by the Aedric spirits) they would really ascend as much as their ancestors forming Nirn would be let loose.
