Buffing fighter damage would mitigate the past pacthes where fighter damage aplication have bren nerfed. It would be completely counter productive to the balance goals set by ccp.
Altho, an really expencive augmented fighter could be cool, but they would need to be “glass cannons”. Bulky enough, that they coulden’t speed tank null anomalies and pricy enough that a coalition carrier fleet woulden’t field them. But as a curriosity or a show of golden balls they would be prety nice.
E: when looking for the next step for your super carrier there are always officer mods, aim for them, some of them even increase your damage quite substancialy.
Carriers, and to a lesser extent drone boats, have on-grid damage projection unlike any other ship. CCP has always been a bit slow to release full module/modifier diversity to fighters and drones, and I suspect this is why.
I’m not saying “no”, just that if it ever does happen it’ll have to have been tested to hell and back, and you probably shoudn’t expect mutations quite as powerful as you get for turrets/launchers.
