I would call my line Merveilles du Monde (Wonders of the World in French) and then have several lines such as:
- The Ancient World line which would be exclusives named such as Pyramids of Giza, Gardens of Babylon etc.
- The Structures line named such as Stonehenge, Hagia Sophia etc.
- The New7Wonders line named such as Petra, Machu Picchu etc.
- The Natural Wonders which would be based on natures scents named such as Aurora, Great Barrier Reef etc.
- The Solar Wonders which would be named Enceladus, Olympus Mons etc.
Looking back...i've thought about this way too much lol.
