It's not Earth-928, so in whatever alternate 2099 this is, Miguel simply has his father's surname, no big deal. If it's popular and sells well, then maybe they'll add some version of Avengers 2099 to the Earth-928 storyline after Secret Wars ends?

As for the destruction of the multiverse, it collapse as a result of the Incursions, but we already have confirmation that it will be at least partially restored post-Secret Wars, so think of the entire event as basically a collection of "What If?" limited series that will end in a couple months.
