Sorry, you can't be a dragon. Dragons as actual player characters do exist, but they're not a race, just special creatures put in for flavor. They don't reproduce.
You could have more luck with your other wishes, though.
And I'm not sure I know every race in FTO, but I do know of at least 13. (Well, it depends a bit on the definition of what counts as separate race because there are a few species that have separate "branches" that are completely independent from each other at different places throughout the FTO world with different ancestors and sometimes also slight variations in their racial description.)
