The target in question is what we call a general morph, in that it affects the entire model when dialed up.
An ongoing project being considered here is a collection of typical body types for standard humans.
What you might want to consider is a toon mod like this one:
http://www.makehumancommunity.org/target/toon_eyes_and_slim_body.htmlWhat this target does is thin out the waist, lengthen the limbs, and shape the face. It creates that classic pixie/alien model when dialed up to maximum. It is very effective for creating all manner of offworlders.
Here is an example:

- Yellow Female Alien from Procyon
Toon Eys and Slim Body target
Other targets were also used, including the ones for elven ears.
