Ah excellent, so it could be possible, so theres no evidence saying that it couldn't happen leaves a little breathing room. I have another question as well! What would the Daedra think of the Aedra? same Dremora, would he revear them or respect them as greater spirits? or do the lesser Daedra hold a grudge?
The Daedra and Aedra are not really like higher/ lower, the difference is more like they are siblings who are estranged because one group doesnt agree with the life choices of the other.
I dont think they would hold each other in high regard but I dont think there is open hostility or war between them.
The lesser daedra are denizens of the various planes of Oblivion, just as the men and mer are denizens of Tamriel.
Tamriel is of the Aedra, Oblivion of the Daedra.
Since the Aedra are bound to the mundus because they gave parts of themselves to make it I dont think the lesser daedra would think much of them at all, as they live in a plane that the Aedra have no dominion over.
Possibly they have contempt for them, but not respect and I cant think of a reason they would hold a grudge.
