I have a couple of fun concepts in mind but I can’t seem to flesh them out on my own. I really like how often FFG captures something about a character with their rule so I’ve tried to do that.
Watto for scum. His dice were a big thing in ep1. So during the game (or before it starts?) you (spend a non-recurring charge?) ask your opponent ‘hits or misses’, roll the dice and then one of you gets a benefit?
Padmé for the Republic. In two of the three movies she had a body double. She has one points cost but requires two cards to be fielded (two ships in the same squad must both have the identical card). When the game begins she does nothing and neither ship benefits from having her, but at a certain point during the game her player nominates which ship she’s really on and her ability kicks in for that ship only. Not sure what that ability should be though. Or just one card and one ship but two get nominated with an effect token (Krennic style) and later one of them is selected to receive a benefit and the other discards their token.
