The setup you want to use should be fine.

Do you mean, are there examples of how to configure these features?
ovs-vsctl(8) has some simple examples.

OVS can mirror to a VLAN (RSPAN) directly.  It can mirror to a GRE
tunnel (ERSPAN-like) if you set up a GRE tunnel vport and use that as
the destination for mirroring.

It doesn't make sense to post a claim of confidentiality to a publicly
archived mailing list.  If you really need confidentiality, you
shouldn't post here; if you don't really need confidentiality, you
shouldn't include such a silly notice.
