Howlrunner plus a bunch of Academy pilots is the most common, making a 7 TIE swarm with good accuracy. Otherwise, maybe you could drop Night Beast and Gundark, replace them with Academy TIEs, and spend the extra points on Push The Limit and a Stealth Device for Howlrunner in order to keep her alive longer. Or replace them with Black Squadron TIEs using Draw Their Fire to protect all the other named TIEs.
Just some of the ideas. I would actually start by running the all-named-TIE list a few times to get a feel for what you want to do to improve the squadron. Then, some possibilities that fit your playing style should make themselves apparent.
