If you want to play around with other shapes (angles, polys etc.) you should have a look at AFMG "Reflex" (BEM-modeling of diffusers) but it does not do folded shapes (... yet, I’ve asked for it when I was in the beta team, perhaps in next version but the demand seems very slim).

I would again like to express my fears about excessive absorption in a folded design, especially if as complex as the above design. If you buy Reflex, you can find good stepped shapes instead thus minimizing absorption:
