The turning of the kalpas does affect what's outside of Mundus. It has to, otherwise they aedra/daedra would not switch places. Now, Aedra are always Aedra and Daedra are always Daedra as kalpas reset at Convention which is after everyone made their choice on where they stand on creation. (of course this is true until something specific changes that such as monkey dancing or Alduin curse for example), but the fundamentals of the Aurbis change. Peryite, for example, is suppose to change places with Akatosh in the next Kalpa. What exactly this means isn't entirely clear though. Could it mean that he becomes chief over the Aedra. Unlikely. He is Akatosh's shadow, so it's possible he is the bound Dragon and time is more diseased and rotting. (Inturpret that how you will). There's also the possibility of some other kalpa having Meridia take Kyne's place. They're practically the same anyway. An Aurbis with Meridia as chief over life would be more of a Tapestry than a Musical. The possibilities go on.

Et'ada can be killed, but their death isn't like mortal death. Lorkhan is the example here. However, Alduin can't do anything about the Aedra because they use the Walkabout which allows them to travers outside the Aurbis while Alduin is om nomming everything. In other words, they take a hike through the Dreamsleeve while the kalpa is turning.

Alduin is trans-calpic because the Nords are. Or more specifically, they probably are. There was a piece written a couple months ago on r/teslore about it. It's one of the more awesome and quite believable theories I've seen in a while.

I think Alduin's claim as First Born come from monkey dancing. The Selectives altered the Dragon with dawn magic and screwed everything up, changed things, and in the end we have a very very Manish Aka aspect who took the place of Auri-El as the first Dragon. My thought is that Alduin was "next" to come out of the Aka shattering.
