Great idea! I've been on projects that tried to use advisory committees in a similar capacity. The failure was that institutions would replace the perspectives of community members (often working-class POC) with scholars who "specialized" in said community members' experiences. In fact, one project used a non-local white male scholar in the place of the local elder community activist of color he interviewed! This definitely gets back to what PubComm's activist session was talking about - public historians get the spotlight and credentials while profiting off the intellectual and emotional labor of their "subjects."
