A way to put fully functional fleet commands on the MC80; ya know, the only Rebel ship that actually gives fleet commands on screen in the original trilogy. Say, a new Home One title that is a Rebel take on the Chimaera title, or else something like Flag Bridge without the token use restriction just for MC80s/75s. The fact that the Pelta is still way better at fleet commands than the actual flagship of the entire Rebel/New Republic fleet is so frustrating.
B-wings that can catch the capital ships they're designed to destroy without needing a bunch of external cards to push them.
And on a much more random note, a new special ability for squadron Wedge, so I can unstaple him from Dutch. Something where he isn't a counterpuncher with escort.
