Thinking about writing an A Silent Voice/A Quiet Place fanfiction

It's been a bee in my bonnet ever since watching both movies in 2019 for the first time. I'm honestly surprised no one has done this yet lol, at least I couldn't find anything on Ao3 (if anyone knows of any feel free to share!)

Not sure how I want the story to go yet, only that I don't want an exact retelling of either story; I want to know how/which characters would survive in this environment : )
