Its a great Post and a good suggestion to bring "old" armor sets back into the game even as event armors.
My suggestion would also be to bring more KOTOR/KOTOR2 armor sets into the game either as an event bonus or even in cartell market for exmple a full armor set of Nihilus and not just the mask.
Also could be a KOTOR themed event a good idea not just some side notes in some Operations or Flashpoints.
