Ok, I was confused because you said "a bomber buddy to feed him a target lock". So I thought you meant feed it to Rexler.

Yes.

Nothing about that requires TIE/D.

Rexler with TIE/x7, Juke (optionally Stealth Device or TIEmk2)

Scimitar Squadron Pilot with TIE Shuttle, Fleet Officer, Systems Officer, TIE Mk2 (AKA Bomber Buddy)

Rex flies out ahead in round 1, then from then on the Bomber Buddy closes up to him, gives him a lock and a focus (and another focus for itself or another ship), then Rex does a 3- or 4-speed move, picks up his evade, takes another focus with his action, and BAM. Maximum mods, with a Juke to knock a die over, and a focus left over at the end for his pilot ability. Repeat until one of them dies or Rex has to k-turn.
