I agree that not stuffing ADC does not make things worthwhile. How about
considering a DSP breakout board similar to the standalone digital box? This,
obviously, is another piece of hardware need to be maintained. But I think this
makes more sense for the application of laser stabilization, i.e.

Yes. This is also what the USRP hardware does. And FMC does ground
shielding for its regular digital pairs as well. Given that nobody
seems to have done an

This links works fine here. Anyway, here is the slightly updated version.
