Where congregational interaction is desired you often want to provide both reflective and diffusive surfaces around and over the congregation, and for mixed use rooms often in combination with some absorptive surfaces as well.

Exactly. It was funny, one of the panelists pointed out that to enhance the congregations perception and involvement, you (generally) want the reflective surfaces close to them, and the absorptive surfaces further away to control reflective and delay issues (which contribute to noise/un-clarity) - yet what do "we" (it was a session aimed at architects) do? We put carpet, padding, etc. near them and hard surfaces like ceilings away from them - opposite of what you want for congregational singing.

And is the 'V' shaped clouds recommendation a result of assessing your specific space and needs or is that simply applying a 'one size fits all' approach?

Nope - it was based on examples for particular spaces - of which ours closely matches. Our space is, in my opinion, pretty flat. Especially during congregational singing. I can see where by altering the clouds and then tuning the system to match the changes, we could enhance the congregational singing for the congregation, as well as toning down some of our stage noise and enhancing clarity for the pastor or other mostly speaking parts of the service. And it's not just the clouds...
Several of the sessions touched on the conflict between reverb being good for most music but horrible for speaking, and flat spaces reverb free spaces being better for speaking and rock/contemporary music - and that Church worship spaces often do neither well for various reasons. It was fascinating to sit in many of the sessions and get exposed to some of these ideas. It may be old hat for those such as yourself, but as I said I have a new appreciation for acoustics and my surround sound at home already has benefited from some of what I was exposed to

And of course the audio system design is part of this as well, minimizing the energy directed at the ceiling minimizes the related issues and can increase the ratio of the direct to indirect energy, thus typically improving intelligibility.

Yup, we recently had an acoustical engineer come in to help us re-tune our space, and not only do I understand why he did what he did better, but why he did some things like changing the positions of some of the speakers, replacing our DSP with a more capable unit to handle the delays better, separating out the subs to help with immersive sound during music but to cut back during speaking, etc. It's amazing what a little perspective brings - I now get it and that's cool
And he also caught some improperly done rigging that we had corrected. It's seriously scary stuff, people! You do not want a 200lb speaker crashing down, let alone on top of anyone!
And I wouldn't undertake re-desiging something like the clouds on my own - I would advocate we bring him back along with an architect that preferably specializes in designing with audio in mind. I have no doubt that by reconfiguring our ceiling, altering our flooring a little and tweaking a few other things, we could totally transform our space acoustically. It will probably be a dream for more than a few years - But I can dream!
If we ever do remodel and if I'm still around when that happens, if nothing else I will be able to ask more intelligent questions and make sure we are getting the best bang for our buck. For any other volunteers out there, if you have an opportunity to attend a local class, or a conference like WFX Expo, I highly recommend it.
