I think we're missing the obvious. A clone Zed95 could fill the same role as the Vulture. It could straight up be a tiny mass number fighter. 2 firepower, 2 agility, because of course. But then give it 2 hull, and a single shield. It gets a torpedo slot along with something like ESC, and some nifty ship rule and BAM! That's a unique little ship, and very thematically fitting to the mass armies of the Clone Wars.
I also want the LAAT/i first though. And it should be a medium. It's about the same size as a U-wing, fills the same role too. It's not nearly as big as any other large shuttle really. The senatorial shuttles, Twilight, and Nu-class are more the large ships to be sprinkled in. Then the V-wings. Charger and Naboo Yacht for Epic.
