Done and done. As I said on the RSI forums, I am a supporter of any and all ship customization. In this game, your ship will be just as much of your avatar as your character. It needs to be just as original and unique as your character.
Reminds be a bit of altering "tire-smoke" for GTA Online. I think if there are enough alterations possible to ships you might actually get "tuner clubs" out there.
