Custom Sprays?

I'm not sure if it's been brought up before or if it's something that's already being considered, but I think it'd be cool if we could have custom sprays down the line (like in NoPixel and whatever other server that has it) as a way for organizations to have a more unique and distinct mark that goes beyond just text and color. I think it would motivate the artsy people in the server to design the sprays and could even create RP within the city if there is an artist that everyone wants to hire, etc...
