:) The ponies already have Greece. Equestria has a ton of creatures and ideas based around Ancient Greece (the Pegasi and the Hydra, off the top of my head), mixed liberally with Medieval Europe (esp. the "ancient Equestria", like Starswirl the Bearded) and the modern day USA...

I [i]did[/i] have a thought for the homeland of the minotaurs, though, and it will probably turn out pretty Greece-like.
