Now, i know there have been other mods that change Bastila's darkside appearance, plus giving her other items. But i think one i would do, has a different kind of spin on it. 
  Such as:

 (Oh great, she just had to blink....)  
 Now, i just have to implement that robe as a new robe, and not her default clothing as it is now. 
 Though i think this will be the first mod i release to use 2da edits, and would likely be incompatible with any other mods that do the same, as i haven't got the hang of the patcher yet.
