Jon Risch, question on Diffusor panels

Hi Jon,
In anticipation of the arrival of a new system, I have the opportunity to completely revise my listening room.
Previously I used SF Extremas firing across the room with the listening position 1-2 feet from the back wall. I used your Bass Traps (8 x 16') and 3 large Absorber panels on the front wall. Overall I got a very well balanced sound with super wide and moderately deep soundstage. Using panels at the reflection points didn't work well, damping 'air' and narrowing the sounstage. Obviously diffusor panels on the backwall didn't fit with the room configuration.

I'm now going to be installing Avantgarde Trios, firing along the length of my room. This will place the listening position 8' or more from the back wall. Since the Trios have a heavily tailored polar response, most of the energy at the listening position will be direct, with some minor floor and ceiling reflections. According the Avantgarde, side wall reflections are not a problem and only rear wall reflections need to be considered.
My question is:
My listening room is empty at the moment and I now have the possibility to install some diffussion on the back wall. I've read your note on Diffusor panels and it seems like a very effective and simple solution. I was however thinking of treating the whole backwall in a more permanent fashion i.e attach the bowed panels at floor and ceiling, bowing the panels in the height rather than the width, attaching only half tubes in the pattern you suggest then painting the whole lot to match the rest of the room. I would stuff the area behind the panels with glass wool then seal so no fibres escape. I would also prefer to use tightly packed glass wool behind the half pipes to prevent outgassing, since the amount of expanding foam would be rather large over the whole wall area. Does this sound like a solution? Do you forsee any difficulties with the changes I'm proposing. Is treating the whole wall overkill?
Thanks again for the advice
Steve
