The blocker isn't TC39 membership or being a champion though. It's blocked on someone actually working on it, writing the docs and editing the spec text, answering the questions brought up etc. If you can find someone willing to do that, I'm happy to help you find a TC39 delegate to help you with the committee stuff (Either with my Node.js hat with our delegate or with my Microsoft one). I'll also guarantee Ben (who is a friend) would be happy to help he just doesn't have the time to work on the proposal itself.
