I had thought that gre tunnels allowed layer 2 packets by forwarding ethernet frames using IP and then stripping the IP header back to Ethernet when they reached the end of the tunnel? Do they not work in this way or is it that this will not work with OVS in this way?
You're talking about the outer header but I'm talking about the inner
one. GRE packets can encapsulate either Ethernet frames or raw IP

You should use the GRE support built into OVS. If that doesn't work
then something else is the problem.
