One of the Starfire books - In Death Ground have this. They used their carriers to cycle fighters from star base to replenish their life support systems and rearm them because they would not be able to reach hostile fleet on their own. But I think that it was one time thing.
I think that specialised module to refuel fighters should be available, we can do it in real life, so I don't see a reason why it should not be available in Aurora.
Maybe if it would be possible to change fighter loadouts, for example to add additional fuel tanks for long range mission, then it would not be necessary to have fighter tankers.
