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.
Yes, something similar to the marketplace, but instead of "buy" offers, you have "scout x region" requests.
