Yes, of course. Pick a GID, replace /dev/fd0 by /dev/cdrom (or
whatever the cdrom device is), and replace the gid=25 by something

Affs mode switch changes all files permissions to the given mode (from the mount manpage). The msdos and iso9660 fs have umask, which is a mask specifying the bits to discard on the existing permissions.
