Have you considered the opportunity of raising your upper bass HP crossover?  How high do you plan to use your mid bass horns?  If your mid bass is comfortable playing up to 280hz (or whatever the right freq is), you can use your upper bass horn to play more conservatively, without trying to push it so hard for maximum amount of bass output.  You can use your upper bass more like a midrange horn, with a comfortable margin underneath.  When the upper bass was the lowest horn in Macondo, it had to be pushed.  Now with the big horns for carrying the load of your low channels, it should be an opportunity for the upper bass horns to be used differently.

Scott, this all will be decided during my experiments the coming days.  I have many ideas how it might be done but let see what will stick to the wall. Still, the first thing I think it to setting up the output of MF and upperbass equal, to make the upperbass and MF to work properly together, then to set a proper operation of Fundamental channel and only THEN to think how to match midbass to it. Without a proper setting up of upperbass there in no way to look for a reasonable midbass upper knee. Do not forget the I did not do anything with upperbass since I move to the new place and I knew that my upperbass dod not has as much room gain as it has in my old home.

Romy, what is the un-labeled "box with dots" before the grid?

Does the wiper track well enough near the top, and will this give you enough slack, to just use total R it as it is?

I do not know what wiper you are talking about. The "box with dots" before the grid are something so-called “grid stoppers”. The 6E5P is very fast tube and as anti-oscillation measures before the grip pit I use a bid of ferrite.
