Rebels need an X-wing title. There are a number of ways to do it and I would honestly release it in a Rebel Vets set and give it two titles like the Tie/d with one title for the E-wing like the bomber.
The two easiest ways to do it would be point reduction and munitions modification.
-Liberated Technology: essentially the original xwings liberated from Incom, stealing is cheaper than building
Reduce the point cost but must equip an Astromech possibly for free, boost PS, must equip IA
-Rogue Squadron: full on strike kit, maximum damage
Equip a free Torpedo, allows chips and IA
