well all races can be changed into lycanthropes and skin walkers are like the offspring of those cursed people. "skinwalkers are those with a lycanthrope crouching somewhere in the branches of their family tree". if an elf werewolf has a family then one of his children or grand children will pop up as a elven skinwalker. just use what race the progenitor was. unless of coarse that offspring was a mix breed say half elf. i would use what ever "base race" makes sense. " skinwalkers are virtually indistinguishable from others of the ethnic group into which they are born. "
there is also the side bar which is under Height and Weight
Sidebar: Non-Human Skinwalkers
Skinwalkers are found mostly in human populations. However, because of the nature of lycanthropy, skinwalkers can feasibly be of any intelligent humanoid race. So while uncommon, a lycanthropic bloodline can descend through non-humans like halflings, dwarves, orcs, or elves.
Non-human skinwalkers perhaps more closely resemble their non-lycanthropic parent race, but possess the same statistics as human-descended skinwalkers with the exception of size and effects dependent on size, such as the damage die of natural attacks. For example, a gnome skinwalker is Small, but otherwise is statistically identical to the base skinwalker race presented here (unless, of course, the character is descended from an alternate skinwalker heritage, in which case she has the statistics of that heritage).
Regardless, skinwalkers of non-human descent are typically raised in the same culture as their parent race, and thus usually have the same cultural understanding and education that anyone in their community possesses. So while a half-orc skinwalker raised in an orc tribe might not gain automatic proficiency with the orc double-axe, that doesn't necessarily preclude him from honing his aggressive battle tactics and learning how to fight like an orc.
