What really surprised me was how good everything sounded with no filter on the upper-bass horns, and all drivers connected to the same (8 Ohm) tap; sure I'm getting too much mid-range from the upper-bass horn, but its not as destructive as I would have predicted.

Yes, Fane Studio 8M does fine in this horn to 4K and it if works alone with S2 then it is not very annoying. However, your Fundamental Chanel will produce much better 500-100Hx then Fane and this it would be a good idea to roll of the Fane sooner. The length of tail that your midbass will output would dictate not the lower MF tone but the vertical virtual centering of your system. If you feel that from your listening distance you will have some minor vertical movement of virtual MF source ten you might let the Fane’s tail to run a bit lower and it will tight the virtual MF source to you center (that I presume is the location of your MF driver). Those techniques are one of the many advantages of Macondo configuration and they were among the methods that allow me to integrate drivers from absolutely insane near-field distance.

Yes, finding the proper level of attenuation should be fairly simple; as previously discussed, I could use the L-Pads already in place (currently bypassed) on all MF and HF drivers to establish the correct level, then build the corresponding resistive voltage dividers.

Be VERY careful and DO NOT use the wirewound L-Pads for MF and HF channels. The wirewound L-Pads are hugely inductive and then eat MF’s and HF’s transients VERY aggressively. Use ONLY not inductive fixed restors.

"...Do the same with tweeter [tweeter and MF I assume] , and then with tweeter and bass [tweeter and upper-bass I assume]..."

What I was trying to say was that adding HF or LF channels shall not affect your perception of the rightness of the MF/upperbass balance. In the rest your corrections were correct. In my post about I did not write anything about Midbass and use upper-bass and Midbass interchangeably. The reason is the nether I not you have the Midbass channels operational.

It is entirely possible that I end up multi-amping the system further than is already the case (a second pair of amps currently drives lower-bass); if not going for full DSET, I could imagine driving mid-bass and upper-bass from a dedicated pair of amps.

I would say that if you do for economic configuration then you would need to drive the mid-bass and upper-bass from one amp and Fundamental, MF and HF from another amp. The key in here do not let the fine MF driver to see the inductive reaction of big mid-bass and upper-bass voice coils
