I agree with your take on it but I have lived in this state a looknnng time and I still wonder if they would interpret a investor-in-the-harvest sharing-type membership arrangement as a version of commercial venture. My educated guess that they would and at the least it would be taken to court which would be a PITA for everyone.

That said, I like the concept and wish OP and the hunter they'd work with the best as it would seem to effectively distribute the resource.
