Reading/writing compressed pages should be possible if you write an SQLite filesystem plugin that de/compresses each page that SQLite requests.

A premade solution, if you have USD 2000 to spare would be CEROD by the makers of SQLite, which allows for compression and encryption.

I suspect that the performance of a SQLite file compressed by a standard tool will be fairly bad as I assume that SQLite relies on seeking within the file while most de/compressors assume that a file will be read sequentially.
