I've scanned through the Seviopedia and found some more suggestions:
Items in () are things witout available graphics/stats.
- Give "Swiss" a discount for "Einsteins Laboratory" --he worked in Zurich,
- (Give Swiss a new Building "Swiss Bank" --we all know that is typical for them, right?)
- Give "Inca" a discount for "Machu Pitchu"
- Give "Cathago" back the "Cothon" Building
- Give "Spain" back the "Citadel"
- Give "Polish" a discount to "Copernicus Observatory" ("Copernicus" and "Chopin", and "Pope Jon Paul II" could be more Polish Heroes, by the way)
-Give "Russian" Back the "Bolshoi"
-Give "Polynesian" and/or "Maori" a discount to "Imu"
-(Give France a Hero "Louis XIV"
- the Sun King)
-(Give the Goths a Hero "Alaric I"

It might be a good thought to split some Cultures, resulting in in less benefits for the Cultures with lots of Heroes/Wonder Discounts:
- The Greek might be "Athens" and "Sparta", Maybe Macedonian ("Alex the Great") as well
- China might be broken into it Dynasties, like "Han", "Ming" etc.
- I don't have a good Idea for the Modern Americans, maybe something like "New England States" and "Californian" might be a start.
