Another idea.
"...there has to be a server on the other side of the client connection obeying its API to tell the client stuff like what map you're on, where you are, where the camera is, etc. That really is the hard part, as writing even something as simple as just a server that allows you to walk around an empty map is a monumental task, let alone anything that would allow you to use powers, fight villains, etc. But make no mistake, there are people working on it."
Okay, that's that. But in the meantime, let's assume our people will be successful, given time.
Right now, we have the Icon program, we have access to our beloved character creator. How difficult would it be to have some of our artistically-minded folks editing the costume graphics files?
For example, a lot of the "patterns" are at a lower resolution because they were created at game release. Let's assume we will actually manage to create our own server. Is anything stopping us from replacing the costume graphics with our own? What's stopping us from taking over "Sexy Jay's" job, and creating and sharing whatever costumes we want? We could also reorganize things a bit.
I myself would love to contribute to such a project, if I knew what programs were necessary and where the graphics were stored. That would keep a lot of us busy and happy.
