Snapshots and Dribbles

What if we saw from the perspective of the Anthropologist in Jeff VanderMeer's Annihilation (book, not the movie)? What if there were an added scene between Henry Dashwood's conversation with John Dashwood and Fanny's move-in to show further character development in Jane Austen's Sense and Sensibility? What if JK Rowling's Harry Potter and the Philosopher's Stone were set in Australia?
This is a compilation of added scenes or AUs I wrote but have no idea where to put (spoilers of course).

Disclaimer:
Annihilation belongs to Jeff VanderMeer.
Sense and Sensibility is within the public domain; however, I will still note that it originally belonged to Jane Austen.
Harry Potter and the Philosopher's Stone belongs to JK Rowling.
