You have really done your homework on the a.r. eqs...
It helps to have blueprints. I'm also quite passionate about this stuff.

The box you are working on sounds very awesome- would you be interested in making it a group diy project?
There are a few factors that make me somewhat reluctant:
Firstly: I try to eek out a living of sorts from various audio related designs or builds and, while I have been, and am still willing to be, quite free with various bits of info, I generally try not to give the farm away in case a project comes down the pike that earns a bit of crust from whatever info I have acquired or a design I may have done. I could, for instance, design a PCB for the above eq and offer it for sale but, since this forum is intended as a "not for profit", I am probably not going to realize much in return. For example, in the Black Market here, I might get away with $5 on top of what a board costs me to make. By the same token, I could build one or a pair of these eqs and realize enough to pay rent for a month. I'm not all about money (I usually lean towards the broke side to be honest) but I
have to be practical.
Secondly: None of this stuff is that difficult to come up with. There are several people who regularly contribute to this board that know WAY more than I do about certain aspects of audio design. No names
This is of no real relevance to what I'm trying to say, just thought I'd throw it in!! Anyway, these days I'm going to try to limit my posts to hinting at things I've found to work for me without posting schematics etc. I think it's important that people go away and try various ideas themselves, that's how you learn. That's what I do with my stuff and I always do learn something or other in the process.
Thirdly (maybe finally?): I have a tendecy to disappear from here for, sometimes, long periods of time. This isn't a good thing if you're running a group project.
Especially if it's your design!! :
I would say it would be quite easy, if you have access to the A.R. presence box plug-in, to plot out the curves. Start playing around with a passive eq circuit in a simulator until you get something close to those curves. After that, build it because that's the ONLY way to know if you have something worthwhile.
