Actually, there's a lore about a Female becoming a Dragon. It's not that great, but I suppose it'll do. It was in The Witcher: Assasian's of Kings, if anyone ever played it.

So, to end this discussion:

1. I believe that there shouldn't be Dragon mounting, Weredragons or Dragon Transformation, because it would make the player a bit too overpowered. If you want to be overpowered, just play on the lowest difficulity with console commands.

2. The Daedra (And probably the Aedra) require a specific sacrfice of either an item of power, a living being or Cheese (If you are Sheogorath. Sacrficing cheese!).

3. The Dragonborn is absolutly unable to take the form of a Dragon, as he devours the soul of the Dragon, and not takes it's physical form.

4. Just get the Arrowsmithing into the game, Bethesda. We didn't even argue about that.
