Currently the rules assume that you are either human or human-like (Twi'lek, Zabrak etc.)
The concept of 'Alien Powers' doe technically exist (and one has eben allocated via custom circumstance to Xeth's Geonosian) but they are not really in othe rules systen yet, and would actually require some sort of general template ruling or their own template.
(The only one we can easily bring back is the Brute, which is a Dark Side template from some vast, physically powerful race, an extreme version of the Corsair with a Strength of 6).
So I am afraid more exotic stuff cannot currently be simulated by the rules.
