I am not fond of your first two ideas. Your third idea is unlikely to the extent that it borders impossible, especially considering your specific choices. Metatron might die in Season Nine, and in fact likely will; however, that extrapolation from random suggestions is not as credible.

Anna is much less of a dick than any other angel barring Cas; her efforts were to preserve humans, as the Apocalypse on Earth really wouldn't harm angels hiding in Heaven. I personally would like to see her return, but there is no basis for it, especially considering Michael completely annihilated her.

* I mention such angels as Michael as "dicks" from the human perspective, due to their view of the species, as is standard of almost all angels.

However, the Nephilim concept of this does not work well for several reasons: the main ones are that it has been done before and that it is simply a nonsensical misreading.
