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!
