Probably not what you had in mind, but I think a TIE fighter pilot with the following Pilot Ability would be REALLY fun: "You may take the "perfom action" step of the Activation Phase before executing a maneuver." I don't know how much he would cost, but I'm guessing 15 or 16. He'd be able to Barrel Roll before he moves, which could get him out of some pretty tricky situations. Of course, if he were stressed he would still have to maneuver first to perform the green maneuver to clear the stress token before he could perform any actions.
I can see it being a lot of fun as a pilot ability, but I'm not positive you even need to remove the Perform Action step (think of Night Beast). Instead, it might be like this:
"When you reveal a green maneuver, you may immediately perform a free Barrel Roll action."
I think it would be fine on a PS5 TIE pilot at 15, or PS6 at 16. Might also be fun on an A-wing, actually, and at PS5 (22 points?) it would give us a named A-wing pilot in between Arvel Skynryd and the Green Squadron Pilot.
Along the lines of my previous ideas, I think I'd also like to something like this as an elite talent:
Last-Minute Adjustment (3): "ACTION: At the start of the Combat Phase, perform one free action shown on your action bar. Then receive one stress token."
I'm not positive about the cost, but I think it's at least in the 2-4 range. It offers an advantage, and potentially a big one, but it doesn't give you any new capabilities--and it restricts your movement on the next round.
