There's actually quite a bit of lore supporting Ishgard now! Really all of the city-states have a great deal of gaps that just have to be filled with with fertile imagination :-]
I think your story is fine generally, and you don't have to listen to any of my advice that follows, but I'll post it since you asked!
I would generally suggest staying away from half-breeds. They are confirmed to exist, but are also very uncommon. I think you can easily build the same theme and concept with something that is more holistic and less likely to raise eye-brows and put radars on alert. Anything from being a suspected of being a heretic (while its unprovable), to competition in romance, or just getting on the wrong side of someone in a position of power would all work for your idea of basically being internally ostracized. Its hard enough to live in Ishgard as-is, following endless years of winter freeze, but certainly having someone with authority trying to make your life miserable would make the lot a whole lot worse! What of a step mother? Or at least a relative who helped raise him like a mother since a soldier on duty would literally not have the time to take care of an infant?
Given the importance of his father to the story, it wasn't clear to me if he was intended to still be alive. If he is, and trying to survive in Ishgard while his son is trying to achieve both of their dreams outside the walls, I think that would provide a hook of considerably more interest than being half-miqo'te
