Yes, there is room to innovate for legal structures, but there are not many ways to skin this cat… As a new structuring community you make the choice about how much to experiment and how much to remix. There’s no streight answer to that. It all depends on the experience you have within the community and how much risk you want to take. It’s all good. Just keep in mind the risk factor and make that choice rational.
There are all sorts of social dynamics in an open groups and everyone’s motivation and incentives to act should also be taken into consideration. Remember the Makerbot story? That mistake was part ignorance and part individual greed and ego.
The transition from informal to formal is very tricky and many communities implode at this stage. I wrote something about this some time ago.

A cultural note, it’s good to be open for constructive criticism…
