Changing the looks only for yourself is easy. Just locate the texture image (MainR.jpg) in the model folder and adjust it using a paint program. Also do the same with the texture files for the spinning rotor disc (top.png and bottom.png). The spinning textures must be .png and have a suitable transparency.
But to have it changeable and available for all is a different story and basically not possible. You could define the rotors as Texture Shape and set the texture files in the .xml - BUT, even this would have no effect on switching the looks of the spinning rotor disc.
