I think it is possible, but I never tried it. I think as long as you can route traffic between gateways, it should work. The routing mechanism can be anything, e.g. regular routing, MPLS, L2 tunnelling, etc. But OVN doesn't know about the mechanisms - it only understands static routes in logical routers. The feature I was thinking about is to support this natively by OVN, so that a tunnel mesh is setup between OVN gateways by ovn-controller running on the gateway chassises. Maybe it is not that important if you can set it up manually (or through external CMS system)
