shared universe

I came up with an idea for a possible shared universe. "The Consignment Shop." Basically, it would be a special shop where second-hand goods are bought, but you get more than the item, you also get the story of the item as well. So a person buying a pair of red FM shoes gets told the story of how they changed the love life of a married couple, and the person buying the wedding dress learns that the last wearer had been born a boy. Stories could be happy or sad, long or short. What do you guys think?
