Hello, and welcome! We have pies in the closet, right below the spiked ceiling that slowly falls.
The NA loremaster has stated in one of his posts (in the official lore forums) that half-breeds do exist, but are extremely rare. It is not stated why, though: it could be social stigma or a biological issue. So, in a purely technical viewpoint, you can roleplay a half-breed. I'm unsure if you should do that, though...but I'll come back to that in a second.
Second: I think the only half-breed in lore is a Miqo'te, but she's a half-breed in the sense he's half Sun Seeker and half Moon Keeper, meaning she has blood of two clans of the same race and, therefore, doesn't really qualify as a half-breed (at least in the sense you are using it). So, no, I do not think there's any half-breeds.
One of our lore gurus will surely corrcet me if I'm wrong.
Now, I'll explain why I have my reserves about going for a half-breed.
The first reason is that it will be impossible to portray visually: the character creator doesn't support half-breeds, so you'll have to settle on an appareance and get used to be called an elezen/hyur depending on what you pick. This is a minor reason, though. Like I said before, there's no in-lore reason as to why you couldn't play a half-breed. There are also ways you can work around it (using descriptions, or even use the lack of visual distiction as a character trait...though that nullifies the 'social stigma' you wanted to use). But, most of the time, people will think you are just trying to be a special snowflake.
The second and most important reason is that, as stated previously, half-breeds are rare. To put it with the words better people than me would use, it's a 'Thing' about your character: something that makes the character special only for the purposes of making him special.
The third problem is with the social stigma. It's dependant on other player characters. If they don't follow it (by not shunning the character away, not disregarding him...by basically being good people, really) then it comes out just as a meaningless trait that only exists to give your character reasons to go into angsty and dramatic episodes.
For your wording, I think you probably wouldn't fall on the angsty side of things, so you might be able to pull it off. My take would to make the social stigma something that pushed him into travelling. Maybe the Duskwight clan he was part of shunned him heavily until he decided (or was forced) to leave. This way you can keep the social stigma side of the character, but instead of being interpreted by others as a 'special sparkly star thing' about him, it will be a part of his history.
Following this thought, I'd personally drop the half-breed thing and go for a hyur that was adopted by a Duskwight (maybe he was friends with the real parents, or he found him alone after the Calamity and took pity on his life) but who was shunned and disliked by the other members of the clan. Duskwights have a nasty reputation and, maybe, this particular clan was quite xenophobic.
I ussually try to stay away from in-universe rare characteristics such as this, as it's like placing a big neon sign over my head, claiming for attention. It sends the wrong message. So I would go for a more mundane and, dare I say, common, character.
