Well, I can sort of fix this...I could use Minmus or Gilly as a template and create a gas giant by super-sizing the planet to say, 5,000-6,000km radius range(or anything else I want) and use the Clouds mod to hide the surface, but give it the Gas Giant feel, It would look like any other Gas Giant, but I can change everything, including atmosphere.(I've had to do this with Neptune and Uranus in the Sol Project). This would take away the green shimmer from the Jool template.
