It shows up in "Wraith Squadron," the X-wing novel that introduces that squadron, in the final battle against ISD Implacable. Admiral Trigit is escaping in a modified, hyperdrive and shield equipped TIE Interceptor along with ttwo likewise equipped wingmen. General Crespin, in an A-wing, uses rotating lasers to pick of one of the wingmen while firing his concussion missiles to eliminate the other. Meanwhile, Myn Donos, oncoming in an X-wing and out for vengence because Trigit ran a mission that wiped out his former squadron, fires his proton torpedoes to take out Trigit while the fleeing Admiral is blinded by his rapidly evaporating wingmen. Donos anticipates the scenario after imagining what he would do while if he were in an A-wing with lasers that can traverse.
Just wanted to throw out the source material. Also, General Crespin would be a great A-wing pilot for this mod to show up as a unique pilot ability since we see him making use of them. He was leading Polerarm Squadron, formerly Blue Squadron while they were in training and yet to formalize a squadron title. Pash Cracken would also be an excellent choice since he's a famed A-wing pilot we don't have yet. Perhaps: Pash Cracken (PS8), General Edor Crespin (PS7) and Polerarm Squadron Pilot (PS4). There were also a few other Polerarm pilots mentioned by name, Dorset Konnair and Tetengo Noor. They're named earlier in the book when two Polerarm A-wings and two Wraith Squadron X-wings, piloted by Kell Tainer and Runt, race through a trench to provide recon on an advancing Imperial force. Noor is seen again in the series, in "Solo Command," and killed when a nearby Imperial ship explodes, enveloping his fleeing A-wing. Later Todra Mayn is named Captain of Polerarm Squadron and is seen several times at squadron briefings alongside Wedge.
Below is a link to a form thread I had awhile back trying to come up with new A-wing pilots based on Polerarm Squadron. All the pilots mentioned above are in it as custom cards.

(I'm giving Polerarm PS4 since Red Squadron X-wings are PS4 and I'm *still* hoping we get a Rogue Squadron Pilot for the X-wing, probably at PS5.)
ALL OF THIS, YES!!!!!
