Contributor community profile?

I created a restricted community and chose to use my real name as the primary profile. When I did that, it asked if I wanted the entire community to use their real names.

I thought about this awhile and decided that people who are only reading and commenting will probably not want to always use their real names or comment completely anonymously. However, I do want the approved contributors to use their real names in order to help build credibility for the com.

Members can surely join a community intent on becoming a contributor so they'll associate their real name, but I'm betting that as the community ages new contributors will most often be members who have interacted with the community for awhile and didn't think ahead to associated their real name.

We don't want people to change user names, so perhaps a separate profile could be created, with a clickable bio that gives a brief overview of credentials, their other username, and maybe their most recent posts?

I'd also expect approved contributors to moderate the comments they generate, so they'd also need the ability to comment as their real name in their own posts, but restricted from it in others, unless they're a leader and speaking officially.
