I doubt it would. We have more than 10 years of experience with realm chatter, and there has always been duplication and beyond. People will read the "I want..." message and reply with a copy without checking if someone else has already done so.
What we would need is a scout reports blackboard, where people can both post and request scout reports.
People do check right now, just that they check the message log rather than "shared scribe reports". I don't see duplicate reports when someone already sent the links to the realm.
