I'm doing something similar but with Vader on Whisper instead, and Deathrain in place of Vermeil. Double Traj Sim makes swarms cry.

Something that seems nice to add would be Composure on Vermiel. Taking a Jam action or a coordinate and having it fail from lack of range is pretty bad. Getting at least a focus token out of it seems like it would be quite handy.

I'm a little mixed on Krennic. In the right circumstances, I don't dislike the thought of him, but I don't know how often you'll want to spend dice, now that you can't spend blanks. Maybe Ablative Plating could be good on Redline... is that worth it? 4 points for possibly saving 2 damage from launched bombs?

I have this odd thought that Seasoned Navigator could be an interesting on a Reaper. Dial in a hard or bank, then you'll still be free to change to a straight, treating it white. Combined with Ailerons, there's a pretty wide swing. Consider: Aileron Left plus Hard Left is 180 degrees different from Aileron Right and Straight. Could be fun to try out, but I'm aware it's probably better on paper than on table.
