First and my favorite example, Au Ra concept art
For the crazy bones that might clip, I'd say let the long ones clip its no worse than what already happens and for like the smaller 3d scales just "hide" them under armor when logic applies. Besides perhaps the most demon like those faces should be fine for the game too (but some of our masks are pretty scary and NPC are fine, so eh..).
Maybe for lore: Iirc Au Ra relate more to the void than dragons so lets use that for the story. One day a scout group from a reclusive mountain tribe of Au Ra wandering through ancient Allaghan ruins found a device that attracted their attention, giving a sense of calling and feelings that it may be whispering- if only they could hear it better. They took it back to their tribe deep in the mountains, where it soon became a fascination to the whole tribe. Water and food became secondary and the facilities began to fall apart, but the tribe just moved closer and closer till their breath buffeted this strange object. As groups of the tribe's people came back from their missions it became too many for those in the back to see this lovely device. So they began to push. Those distracted from the glory that was became enraged and began to violently squabble back and forth. This broke out into a full on brawl with much bloodshed. Too distracted to look at their feet the blood was defying gravity and moving towards and into the device, beginning to glow a sickly red. After a few days the device had it's fill, it began to hum causing the ruckus to die down. A were few dead but most just badly injured, everyone starving. Here the device violently ripped the core of their mountain homestead from it's place and thrust it into a void much like the one you find in FFXI Limbus.
Once in this dark limbus and after the panic had settled down they began their cursed trapped life, creating a sort of shadow kingdom and kingdom no one knew existed. The time they spent there was strange and didn't move at a pace like ours. Over their generations their offspring began to show signs of the void in their scales. The problem for them is they've reached the edge of attainable space of their little pocket and are now forced to keep strict birthing laws and punish those into the endless abyss who fail to follow. Some have grown accustomed to their little kingdom but others have never stopped trying to get out. Our WoD/WoL will trek into this mountain and begin to peel away the gate that keeps them sealed away. Once we have access to Limbus we will have access to this type of Au Ra (race option) and will help the shadow kingdom in powering bridges to other areas of limbus not known of previously via bridges of light (and suffer a lot of political fallout from those who differ in how the void-born kingdom should continue to exist).
Later lore could reveal the Allahgan were trying to see if they could create/summon a void primal one powered by dark crystals, the facility found had been emergency shutdown (while Allahgan were on top) because the orb began to whisper and temper in usual ways (void-temper). What was found by Au Ra was the device that held a pocket of portable void space created by the Allahgans as a breeding ground for a void primal, that pocket known as Limbus (and the Au Ra therein trapped on one of Limbus's sectors).
A very neat lore point could be finding out they were able to send out a few via a great spell that cost them some of their best mages (which is why they haven't done it again, no one is good enough to do it again yet). This was in advance of your arrival to the city, but they haven't heard back from these sent-forth Au Ra. So you could technically start the game as one and it'd just be on the way through this forced exit of limbus you had a concussion (aetherial concussion, lol) that removed memory of how you came to be (so you didn't remember to go back and help save your people), when you finally make it back in the story there could be a few special dialog lines.
The male Au Ra would be a lot of things added/extended (scales/horns), face options, but the general skeleton shape/model would be the same or at least a scale of the same (just things added onto it)
The female Au Ra might require another race's skeleton with tweaks, to be more like the succubus (maybe even Viera skeleton scaled down slightly and made "plumper")
