Okay, so I recently came up with a great idea (you can decide whether you agree or disagree). You know how Xur sells the sparrow upgrades (which change the flame color). What if he sold something that changes the color of your Ghost's eye!? It would work, considering that the ghost only has customizable shells, and not eye parts. It would be a phenomenon, and simple. Xur sells a certain color for a certain amount of coins. I would like to see this happen, but I don't know if it will. Feel free to back up the idea if you want to see unique Ghosts. Thanks.
