It's late and I haven't really thought through the premise too much, but Sai with ST-321 and Emperor Palpatine is 62 points, only 1 more than the classic Redline build. She isn't as mobile as Redline used to be, but she fills a somewhat similar role: hits like a truck, and eats incoming fire that could be going onto other more important ships.
For an easy example, keep things as close as possible to Philip Booth's System Open List. I mean, this doesn't seem bad to me:
- Whisper (Juke, Fifth Brother, Advanced Sensors) 78
- Soontir Fel (Predator) 54
-
Lieutenant Sai (Emperor Palpatine, ST-321) 62
- Total 194, bid 6
Having played with Palp a bunch with double Deltas, I think he's kinda decent. He's not 1e good, but seems totally worth his points. There's often someone who can benefit from an eyeball conversion. Saving a point of damage on Soontir can change a game. But then again, when I was flying him the most, a lot of other folks were playing Juke, and that certainly opens opportunities for Palp to do work. I'm not really into a long Palp discussion; I'd rather keep it on Sai in general.
But Palp is also totally replaceable. Collision Detector has proved its mettle on Upsilons. Sloane can be painful to face, even if she's in a low ship count list. Vader crew is pricey, but activating Whisper's Juke is nasty, and the shuttle even has two arcs to use. Even Krennic doesn't seem too bad: Soontir might want to use Optimized Prototype to save his focus for defense, and ST-321 means there's a decent chance Krennic's ship has actually got a lock on whoever Soontir is shooting.

Anyhow, that's just one example. Taking out an old Redline and putting in a Sai might have some potential.
