[Custom sky animations: Could custom sky animations i.e., different moons be created for sims ?]

I was wondering if the single moon for the night sky might be replaced with other phases and numbers of moons.  I have specifically Gorean role play sims in mind (there are about 400 by a recent count).  Gor is a sci-fi fantasy world with three moons.  I think this would be very popular among afficionados of that genre.  It would not seem like a difficult thing to create, and plenty of talent would be willing.

Thanks,
