By this do you mean that you have iscsi luns which you have configured
lustre to use for it's storage and serve that to lustre clients?  Or do
you mean that you have configured a lustre installation and now want to
re-export the filesystem from lustre clients to other clients via iscsi?

If you mean iscsi as lustre's storage, if it's a block device, lustre
can use it.  So if you configure your iscsi luns on the lustre servers,
you should be able to configure those luns into the lustre filesystem.

I'm starting to feel like you want lustre to be an iscsi "service".
That's not possible.  Lustre presents a filesystem, not storage devices.

For what you seem to want, no.  There are no plans of that nature at all
in the roadmap as far as I know.
