No.

I should mention, there is a mod that will allow the minors to expand, not quite on the level of the majors, but thats 8 more races colonizing at least.
Check this thread out, the link is in the OP, iv'e never personally used it, so i can't help you out, but i'm sure Tolmekian will give you any advice you need.

No, that was me - the AAR I've been writing is about the first game I played with that mod, and while it needs tweaking (the minor-Yor were crushed, and the fact that I still haven't met the minor-Thalan by 2234 suggests they aren't doing so hot either) the idea is basically workable. But there's no way you're ever going to get a full set of genuine major races in the game.
