I've been messing around with a Rebel ARC-170 (Yes, the only time they show up in Rebel hands is during Galaxies, where basically every Clone Wars era ship is just awkwardly shoehorned in for no reason. But it's a ship that suits the Rebel style and they are well known for using salvaged Clone War junk in their forces.)
I like the ARC-170 for a couple of reasons. First, it's a cool ship, one of my favourites from the prequels. Second, it has both an Astromech and multiple Crew members, something unseen so far for Rebels (I went with a single Crew icon for my card, representing the copilot. The gunner is actively engaged on the ship, similarly to the Y-Wing.) Thirdly, it's a small-based ship with a Rear Auxiliary Firing Arc, which is a neat thing that doesn't exist yet.
The costing is extrapolated from the similarity of its numbers to the T-70. While it has a worse dial, the Crew upgrade is definitely a lot more flexible than Tech (At least currently).



Unfortunately, the rear arc provided in Strange Eons is quite hard to read on a small base. I might need to fiddle with that myself.

Seeing as we're in the realm of fanfiction already by giving Rebels the ARC-170, why not stick a familiar face in the cockpit. After all, who's going to fly one better than a Clone?
