I'd guess that they would get the standard classes that Undead can be, and they have a special trait attached to their allied racial ability that alters Hunter specific spell effects to be shadowy/Dark Ranger-y (obviously toggleable somehow).
This is their first step towards class skins, while also adding a hotly requested allied race with little to no real effort outside of creating a few new skin textures, hell, they don't even really need to make new hairstyles, but it would be nice.
