Pikkel Sisters

The Pikkel Sisters was an alias used by the Pike Sisters (Zan Pike and Zu Pike). They used this at least once while working for Savan, trying to recover the HRD Guri. While the "new" name wasn't exactly one of the most clever choices, it is assumed that they also changed their surnames slightly while using this incognito.

Behind the Scenes
The artwork of Shadows of the Empire: Evolution also seems to point out the circumstance that Zan and Zu use artificial lenses on their eyes to cover their true eye colors. Several close ups show the "Pikkel Sisters" both with brown eyes.
