Alternative, fair use solutions for when you can't host a virtual read-aloud

For the past two years, our library hosted a 24-hour read-aloud; where people camped on the front lawn and took turns reading 6-7 books. Due to COVID, we can't hold this event in person this year. Our thought it that we could do it virtually - and instead of reading an entire book, we would ask readers to read the first chapter from one of their favorite books. They would film themselves reading (or we would film them) and then we would post the clip on our YouTube channel. One clip a day would be posted - for a total of 24 clips.

Our questions center around copyright infringement and fair use. Could we host such an event? Would this qualify under educational fair use guidelines?
Could we leave the videos up indefinitely -- or would it be better to have a specific time period and then they disappear?

Any guidance - even if it's a "don't do it!" would be helpful!

Thank you!
