Additional art for higher space station stages

Currently there are a few splash images for the space station that show up at different levels of construction, with space station III or IV having the largest station visible on the splash art. Higher levels do not display any bigger of a station. It was a very cool feeling to watch the station start getting bigger, and some sort of graphics for higher levels of space station would be nice. I'm not sure if that would be more new stages of splash art, or a 3D model of some kind (The first thing seems much easier).
