This is the part with allowing libvirt to override the backing file. Of
course, this is not something that we can add with five lines of code,
it requires -blockdev.

It can be done without blockdev. Have a dictionary that translates filenames, and populate it from the command line (for a bonus, translate a filename to a file descriptor inherited from the caller or passed via the monitor).
