Several months ago I've made a proof-of-concept of exactly what you're talking about, feel free to check it out: https://shekhirin.com/sqlite-fs/.
I recommend downloading sample DB, writing some dummy query like "SELECT BILLINGCOUNTRY, COUNT(INVOICEID) FROM INVOICE GROUP BY 1 ORDER BY 2 DESC" and then pressing Execute.
I've been planning to write an extensive article about it and open sourcing the solution cleaning up the code a little bit, but still haven't got much time to do so.
now let's see what it takes to make absurd-fs, where we use https://github.com/guardianproject/libsqlfs to make a filesystem on top of sqlite on top of the File System Access API.
gotta keep ourselves fully looped! ⥀
(is there perchance a repo available with your work? that'd be lovely to see.)
