In a smart webserver this could mean not a whole lot more than a memcpy, and between you and the CDN it probably won't be too high latency.

One would have to version the SQLite DB by version to avoid corruption by cache invalidation.

My static file HTTP server called "filed" [0] will satisfy a request in as few as 1 system call (no memcpy involved -- the kernel reads the file and sends the buffer to the NIC), by using sendfile(2). Most other webservers do a bit more work, like open the file for every request.
