I'm not expecting Larian to let you play as a non-human.
There are 6 main races, from the humans, to the stout dwarves, tall willowy elves, the Lizards, and gorilla-like orcs and the scrawny imps. That's a lot of different body types that you'd need to model different armors for. That's 12 different race/gender combinations, and can you customize your appearance on top of that? Is the race cosmetic or does it affect the story? That's a heck of a lot of things to worry about, resources to spend. That's why Larian said that different races for the main characters was not happening in Original Sin.
