No. This is very similar to SYSTEMD_UDEV_CUST_RULES and that turned out to
be a bad idea.
The problem with stuff like this is, that as soon as BSPs get a little bit
more complex, options like this start to conflict with packages that want
to install individual files from these directories.

And in most cases, there are other files that are installed anyways to use
the functionality provided by the modules that are loaded, so the config
file should be installed together with those anyways.
