Very good experiment.

I would be curious as to how far you could drive ribbon cable with the RPi and under what termination options.

This sounds a very interesting experiment. I think that just making a better connection, more curated soldering and shortening all that possible (without soldering the resistor on the CPU [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-93934fa1-5cec-4b7b-ab4c-bc6af6608c8d/contentimage_5F00_3.png:16:16] ) you get better results. And by your analysis, it seems you are not so far from success. This kind of connection (maybe only for analogies) recall me the Novell Ethernet cable or - better and before - the Apple CORVUS coax network cable. When there was a problem of reachability of the NE2000 Novell boards we were just adding a resistor in series.
