Yes, if it was a crew or a group project as you say, it would explain why Craig Wright is so confident and arrogant when he claims to be Satoshi Nakomoto, he knows it was a team, and he belongs to it one day, or he considers having fully been part of it at least, and thus being one of the several Satoshi Nakamoto existing. IMO Hal Finney was the main author of the white paper but he wasn't able to code, to test and to market it alone, so he asked some people to help him for free, against IOU or just cash money.
