We can talk about even more general idea of saving file space: compression. Ever heard about it used across the whole filesystems?

Microsoft MS-DOS and Windows supported this in the 90s with DriveSpace, and modern file systems like btrfs and zfs also support transparent compression.

Most compressible file formats are already compressed, and with compression you lose efficient non-sequential IO.

You introduce overhead on both read and write without being a better solution to OPs problem.
