Aside from Akatosh, not a single Divine even existed at the time of the Dragon Cult, as these are Alessian inventions. Alessia was never a part of the Divines, but she is a part of Akatosh. Most of the Dragon Priests have staffs that you can make yourself in game and are able to be found anywhere. Their power and their masks are all stated to have come from the Dragons. There are well over nine of them. Finally, Magnus is not even one of the Eight, so really this makes no sense either way.

The rest of what you said is theory without basis.
