Do you know/have experience with functional subgrouping? If not: google on SCT/functional subgrouping/Y. Agazarian.
Some of my (synnervate-)colleagues are highly trained&skilled in facilitating/applying this and we use it to have a very personal/relational conversation with each other, in which the undercurrent (of unspoken assumptions, opinions, worries, etc. in the relational space) can surface.
The goal is to integrate different perspectives and resolve conflicts. In our case it helps us to adress the 'storming' fase of our development as a group/org. It gives us very intense conversations, not necesarily comfortable, but great depth.
SCT partners great with Holacracy for us: made from the same systemic/holistic worldview.
