You're the first person to suggest that kind of configuration, so thanks.
We ended up purchasing an 8-wave DWDM from our transport vendor, as it
solved the problem and gives us a path to future growth.

Why not using a duplex 120km and a circulator[1] ? This could be far
more reliable if you avoid PC connectors on the way.
You may also mux several DWDM waves using this and a low-loss mux (found
<1.5dB for 8 channels).
Of course, for such lenghts, you may need a chromatic dispersion
compensator.
