Sanest proposal so far.  Just put filenames in separate arguments, as
with almost every other program.

Instead of name=, let's use id= from Gerd's qdev work.

Why "-drive.ID.NAME VALUE", "-net.ID.NAME VALUE" and so forth, i.e. one
option per object with parameters?  Assuming the ID name space is flat,
a single option suffices.  What about "-set ID.NAME=VALUE"?

Quoting is problematic.  Not only because it necessarily breaks some
filenames that used to work, also because the shell quotes, too.  I
don't enjoy counting backslashes.
