I've come around to the K-wing. A little FFG magic, and it will fit right in. I also think there could be some interesting ways to interpret it into the game. Along with the T-wing and R-41, the H-wing looks like it would be interesting as well. And then there are the larger ships, like the YT-2000, the Raven's Claw, and the Pulsar Skate. The Lady Luck/Jade's Fire might be a bit on the big side.
So, at least 10 more possible ships? Depending on how deep FFG goes into the lore (they do dumpster dive). That's good for a few more years.
