Great project. I've long thought about creating a static-site transformer for wordpress sites via SQLLite-- in order to reduce costs and improve security.
The idea would be to feed the wordpress content into a sqlite DB and re-publish the entire site as a static site. Since wordpress comments have declined in usage, this should work well.
Publishing time would be a bit slower, but reads will be 100x faster and 10000x cheaper.
Wordpress now has (almost production ready) SQLite support, and there’s plugins like https://wordpress.org/plugins/simply-static/ so this might already be possible.
