I suggest starting with a Google Group. That's trivial to set up. I'd be interested in participating too.

I wonder what success looks like?

Here's another use case to add to "squishification". Some weeks back, I was exploring how temperature is taught, preK-12. I noticed that mention of 'Sun heats Earth' was wide-spread, but that 'Earth is cooled by the deep-space sky' was almost never mentioned. Half of the energy balance was ignored. So explanatory leverage is left on the table - "Why are nights cold? Especially with clear sky? Especially in the desert? Why are mountains snow-capped? Why is winter colder?" etc. It doesn't seem inaccessible - "Between bright hot Sun, too hot, and dark cold deep-space sky, too cold, Earth spins, mixing too hot, and too cold, into not too bad." Like a person huddled next to a campfire or heater, turning around to warm their back. Spacecraft "barbeque roll" thermal management. Earth's surface as thermal mass for peak smoothing.

Maturing the idea to that point, and then finding and fleshing out opportunities for leverage, benefits from a diversity of expertise. Physics, teaching (various ages), engineering, planetary geology, etc.

So I wonder if it would be useful to think in terms of not just discussion, but also of leveraging existing communities? Orchestration, federation, cross pollination. So bits about radiative cooling rates could go to PhysicsForums.com; about 'why the sky is cold' to /r/AskScienceDiscussion; about 'nice videos of spacecraft doing bbq rolls' to /r/spacex; about teaching aspects to... sigh, it's a mess of mailing lists and blogs and... well, maybe prototypes to teacherspayteachers?; and so on. All pointing back to someplace able to coordinate the input.
