This sounds amazing!
Community manager can be a lonesome profession, we’re often solo-practitioners and many of our direct colleagues don’t understand our craft. Having peer support has been vital for my career and I’m very happy to see you suggest this initiative! 
While I no longer manage a Discourse community, I would love to help out and/or observe a few of your meetings if that’s alright with you?
My background is that I’ve been in “community” for 15 years or so, ran a Discourse forum for 5 of those. Currently I’m a CSM for the Discourse Enterprise customers and I run the Discourse Gold program.
