I cannot answer your question directly but the guys at https://encode.org/ are working with what they call a "For-Purpose Enterprise" which also takes into account altering the operating agreement and implementing dynamic equity split calculation to interface Holacracy with old law-structure. I don't know if you heard about this but if not then it would be a good place to look for some info on this.
Also you can check out a webinar by Encode on this topic: Upgrading Legal Structure.
Hope this helps. Best regards!
