I'm wondering if GIK has considered developing a random-perf panel that could be used as an alternative to the scatter plate, to give 2D diffusion. This would be similar to products made by RPG (BAD panel) and Kinetics (TAD panel). Those are also more fine-grained than the scatter plate so (I believe) can be placed closer to the listener. I suppose you could call it a GAD panel. Or is there some reason that you believe the concept is lacking?
