Only if Emperor in your fleet, who hasn't been printed yet.

My first thought for Piett was to have him come as an officer upgrade and a commander. Have the officer card affect the efficiency of his ship (I believe he was where he was because he was considered a capable ship administrator, if an uninspired admiral), but also have a mechanic that you can discard your commander on the same ship and replace Captain Piett with Admiral Piett.

Captain Piett: Your ship cannot attack fighters. Once per activation add one red die when shooting at a medium or large ship. While on the same ship with your commander, at the end of any turn, you may discard this card to replace your commander with Admiral Piett. 2 points

Admiral Piett: Your large ships are considered obstructed when shooting at fighters. Your medium and large ships may add one red die to any shot they make from their front arc when shooting at long range. 22 points
