I don't think that's possible.  But note that the setup I'm proposing
only needs to be done once at container creation, and could be supported
in templates.

Once set up, usage would be:

host admin:

mkdir /lxcshare/cdrom
mount /dev/cdrom /lxcshare/cdrom

container admin:
mount --move /lxcshare/cdrom /mnt/cdrom
