This is a great idea! You should also weave the previews throughout the show itself if you plan to have any breaks or changeovers. Flood the place with clips 100%. One thing that is highly underrated is writing about the show in a blog or Nostr long form, then writing an article (or having someone backlink) about the article on a (or many) normie blogs.

Be sure to embed trailer in blogs, with next video as the full feature. 😉
