However, I do wonder if the OP has considered dumping IP and just

One of those damned if you do, damned if you don't things I suspect.
One could go with direct Ethernet, but then one has to segment
oneself, as well as deal with lost traffic. One does have the
advantage of being able to use one's own retransmission timeouts.
Having doe that though, some months later someone will want to be able
to run the application between two sites, without any bridging
available and then the lack of routing (since we've ditched IP) will
come back to haunt.

Also, with direct Ethernet, there are only so many Ethertypes/SAPs one
can use which may make multiple "connections" a bit difficult. The
author might have to write her own connection multiplex/demultiplex.
