David, the multiplexing isn't the hard part. The hard part is finding a
way to separate the two signal bands without creating a discontinuity in
the channel impedance. If you can make your own silicon it seems that
could be done. I don't have any good suggestions on how to do that with
any existing FPGA at appreciable line rates.
I think that your life will work out much better if you steal a small
amount of bandwidth higher up in the protocol stack than if you try to
get tricky with the physical layer.
Steve.
