Yeah, I think it's dumb that you have to be a human noble to marry Alistair in the game. I'd be less annoyed if they'd let a human mage be queen as well. But I think that if you harden him, Alistair should stand up for his love and make me queen even if I'm an elf damn it!
That's a matter of Ferelden law. They don't actually have any laws about illegitimate succession--that's more of a modern social thing in the nation. Allistair muddled his claim to the throne by becoming a Grey Warden, not by being a *******. Technically, Wardens can't hold titles, but the Landsmeet sorta compromises. Alistair doesn't actually become king, he becomes Prince Consort and "resigns" as a Grey Warden.
The laws against Mages holding titles is much stricter, and a Mage can't "resign" as a Mage, so its no surprise that you can't become Queen. They're already stretching the law thin to allow Alistair, no way they're going to stretch it any further, particularly for an Elven or Mage Queen. That would just be begging for future civil war. The Human Noble actually enhances his position, being the daughter of a highly-respected Teyrn, so it's a completely different story.
As for inter-species children, Elf + Human children appear fully human, so it is seen as a betrayal (there's a very good chance that Alistair is actually the child of an Elven Mage Warden named Fiona, who didn't want Maric to tell Alistair where he came from out of shame for being what she is). It's confirmed, somewhere, that half-Dwarves are possible (but incredibly rare, due to Dwarven cultural prohibitions). Wiki doesn't say anything about half-Dwarf, half-Elf children. I'm going to guess they almost never happen--there are already strong prohibitions against relations outside their cultures on both sides, and these two groups would have far less contact than with Humans.
If not her, then I could always go for the man ****. 
Do you ever hear anything about the consequences of that decision in Awakenings or DA2?
