Sorry, I thought it was what Creamsteak asked us.
About etiquette... You know, Unicorns are rather barbarians...
The Crab can also be rather uncultured, though I suppose it's all relative. To the Crane, the Unicorn are crude barbarians. To the savage horsemen of the Burning Sands, the Unicorn range from 'no different from the rest' (The Ide) to 'getting soft and settling down' (The Moto).
Should be no trouble adding ancestral feats, I can list feats as needed.
Another comment, Rokugan tends to use armies, rather than total warfare. The same has applied to the Shadowlands, even for their recent invasion of the Empire. Rokugan added the skill 'Battle' to reflect tactical skill and the ability to manage troops. Since the IR tends to have occasional warfare

, this might be worth incorporating.
For clan advantages, that should be doable. The Crab Clan do indeed specialize in fighting from heavy fortification and against the shadowlands. The Crane are the masters of dueling (A frequent tactic is to challenge the general of an opposing army) as well as politics. The Dragon are remote, nearly inaccessable, and are the only clan that have Tattooed Monks. The Lion have the best army, not simply in numbers but in traditional tactics. The Mantis control the seas, having the largest and best navy. The Phoenix are the masters of magic. The Scorpion are the masters of secrets, spying, ninja, etc.

The Unicorn have by far the best cavalry in every catagory.
