Green Squadron, or Green Group, was the name of a number of starfighter squadrons that served the Rebel Alliance and New Republic throughout the Galactic Civil War. The expantion box could come with two starfighters, 1 X-wing and 1 A-wing. All pilot cards could be unique.
1. X-wing
Stevan Makintay , also known as "Mak," was a Human, When the Galactic Empire annexed Hargeeva in 7 BBY, Makintay used the opportunity to attend the Imperial Academy and learn how to pilot starfighters. Makintay flew T-65 X-wing starfighters for the Alliance, and was stationed at Echo Base on the planet of Hoth as part of the fighter complement. After Hoth Makintay was transferred to Eyrie Base on the planet of Karatha, where he commanded Green Squadron.

3 .A-wing
Green Wing was the call sign of a male member of Green Squadron, a Rebel Alliance RZ-1 A-wing interceptor unit that fought during the Battle of Endor in 4 ABY. During the Alliance Fleet's engagement with the Imperial Navy above the Forest Moon of Endor, Green Wing flew into combat alongside Gold Leader General Lando Calrissian, Red Leader Commander Wedge Antilles, and Blue Leader Merrick Simms in an attack on the Empire's main communications ship, which had been jamming the Rebel Fleet.
As the four pilots moved in on the Star Destroyer, Green Wing's starfighter was hit by enemy fire, and he crashed into the communications ship's forward batteries. This sacrifice enabled Calrissian and Antilles to destroy the warship—though Simms was killed as well—and stop the Imperials' jamming of the Rebel flotilla. The Alliance forces would go on to destroy the second Death Star and win the battle, despite many casualties.

4. A-wing or X-wing
Jake Farrell was a Human male starfighter pilot who served in the Galactic Republic prior to the Declaration of a New Order. Following the rise of the Galactic Empire at the end of the Clone Wars, Farrell became an instructor for the Empire, but retired from Imperial service after a series of increasingly ruthless missions. He eventually came out of retirement and joined the Alliance to Restore the Republic, teaching Rebel pilots the skills needed to fight against the Empire. Known as a top X-wing pilot, Farrell flew a modified R-22 Spearhead during the Battle of Yavin. His experience with the R-22 led to him being selected to help design the new RZ-1 A-wing interceptor, which was based on the R-22. When the first A-wings entered service, Farrell transferred to an A-wing squadron.
By the time of the Battle of Endor in 4 ABY, he was considered to be among the best A-wing pilots, and so was chosen to fly with Green Squadron in the assault on the Imperial battlestation, the second Death Star. Participating in the starfighter attack on the Death Star's main reactor, Farrell followed the order of Gold Leader Lando Calrissian to break off his run and head for the surface of the station, drawing off some of the Imperial TIE fighters in pursuit.

I also think this could be the start to additional expansion like Rouge Squadron or Blue Squadron. Example for Blue Squadron you could look for new pilots like Keyan Farlander, nicknamed Lucky. This is just an idea.
