Since you're going for sound design, I would skip the Azimuth since panning and stereo width are things that would be more important farther down the signal chain and could be (mostly) duplicated at your mixer. To give you a wider array of sound tweaking (and give you more patching options for your Quadra), I'd replace the Azimuth with an ADE-10 Reactive Wave Shaper. Other than that, looks like a fun set of modules!
