Too late now for points, but just the other day I tried to imagine your plan. and I was pretty close.
Actually, it is a bit like what I have going now;  15" Eminence bass guitarr woofers in a sealed 3 cu ft cabinet,
Oris 150 with 8" B&C midrange driver, JBL 2435 (carefully filtered) on 340Hz Lecleach and
Fostex T90A gently on top.  Oh, and a tapped horn in the 25-45Hz range. 
To gain midrange resolution I aim to implement JBL 2482 on the Oris via an extender.
The 340Hz horn is too large, so 600Hz on the horizon, perhaps with field coil.
This will also provide space for a more refined ribbon top.
No room in this house for 60Hz horns.  I like the sealed upper bass solution.
I am at a loss for a more refined driver.  Even at 200Hz, second order the quality is very important.
You are satisfied with the upper sound of the 416's.
The best soiund I had on the Eminence was with a Marantz 8b that I had for a very short while.
Nice rosin growl on the cellos!
Hope you will realize the Cetla plan!

My plans are will wary from how the project will end up. If somebody pays me my $50K then it will be a complete, properly balance and well performing speaker with amplification. If I keep it for myself then it will be more like a pile of conceptual channels as I do not need from acoustic system in my fireplace living room any “pushy” sound.

The Altec 19 came to me accidently and mostly due to the residue of my stupid Christian repent.  About a year ago a local audio guy was complaining to me about his loudspeaker and was asking me what to buy for little money. Since he was jazz listener I advised him to get Altec 19 but I warned him that it will require modifying them. Unfortunately people hear only what they want to hear and my comments about need to modify them were discarded. The guy went and bough a mint condition Altec 19, the cleanest that I ever with the newest drivers I ever seen, brought them home and hated the sound. I was in his home at that time and I understand what he did not like but we heard them so differently. Knowing how Altec sound I discarded in my mind all things that are bad about Altec, knowing that it might be dealt with by modification. He did not have the luxury of my experience and he was very pissed with the result – here is one more of my “recommendations” burned in hell. In addition the guy wife did not like the look of Altec 19 in this room and the guy was appearing as he just was raped by Sasquatch. At that time I was moving the things from my storages at my new home and looking how frustrated he was I decided to take those “recommended” Altec 19 from his hands. I always liked how Altec 19 looks like and they looked very nice with my new mahogany-red floors. Yes, some moronic people who do not have furniture buy speakers to fill the room.

I still like very much how the Altec 19 look in my fireplace room. The room is not being used in my house but at winter I do burn fireplace a lot – I love watch at fire. The fireplace room is too far from Macondo and it is a good idea to have some local speakers in it. The quality of these speakers in absolutely irrelevant however. If I sell the Cetla for my $50K then I’ll probably might be able to write off my fireplace room as some kind design facility or demo/testing room…
