I'd try splitting the solution into two devices: at the lower layer, the
tunneling part, which can be done with any traditional transport-layer VPN
solution; at the higher layer (prior to encryption), the TCP enhancement
part, for which, I'd look for dedicated and specialized multipoint WAN
optimization devices.

That's brave! I'd check with the satellite provider if they are able to
forward your frames directly from VSAT to VSAT without going through the
hub, and, if multiple satellites are used, if they can route between
satellites. Most don't. Those two above are NOT easy to do. They will most
probably make your packets "double-hop", so your latency will be about 1.4
seconds.
