Yeah, yeah, we saw your post before. So because dragons can shape shift and one person in the history of Nirn was able to transform into a dragon(permanently mind you) that some how lends credit of explanation as to how we can shape shift into a dragon?
and why not? dragonshouts are abilities that we acquire by "absorbing" a dragon's essence and are used by dragons. who's to say one of them isn't the shapeshifting ability? i can't find anything in the lore that says clearly that by this method shapeshifting into a dragon isn't a possibility.
it might not be in the game but it sure seems to me that it is a viable way for the people that want to fly/fight as dragon while keeping true to the lore.
