Hi Chris, James, Shawn, Thanks for the suggestions - I think they are quite relevant. I will modify and update soon.
I kept the page size as 512 without rowid and dropped foreign keys so I could use it to demo SQLite on a low memory SoC ESP8266 (see https://github.com/siara-cc/esp_arduino_sqlite3_lib/). Since this db would be useful for a larger audience, I will keep separate copies.
