IC: WEG Star Wars
I remember WEG Star Wars so very fondly. I'd be tentatively interested, but I'm checking on the health of a few games first to see about time commitment levels so take my thoughts with a caveat.
Rebellion or Privateers would be my top votes. Liberating a sector would definitely be more interesting than liberating a planet--or if the focus is a planet, doing so by interacting with extra-planetary conflicts, etc. It's just not Star Wars if it isn't hopping exotic planets, if you ask me. Privateers would be interesting as a private concern focused on corporate or small-scale governments, but quickly getting wrapped up in the Rebellion because 1) the rebels are desperate and hire them, and 2) the Empire is leaving less and less room for them to operate (semi-)legitimately. I mean, if the Empire starts labeling them as rebels anyway...
I could see two ways to go with a ship-based approach. One, don't focus on the fighters but rather the capital ships, in this case probably a smaller capital ship but still big enough that everyone has a role aboard during action. The other approach would be to make it a Rogue Squadron-type group but just give out some starfighter skills as an automatic baseline for everyone. With only 7D to spread around, "starfighter pilot" would be a niche in a mixed group and take up most of those skill points, but if everyone is a pilot you end up with pretty much the same skill set across the board (or else incompetence as a pilot, also not fun). But if you just gave everyone a starting package of (and I'm making this up from old memory here...) 2D Starfighter Pilot, 2D Starship Gunnery, 1D Starship Shields, 1D Sensors, or something like that, and keep the 2D cap at char gen, then everyone can use their free points to focus on what they are other than a pilot. It starts the characters with extra skills, but with the 2D cap it's just extra breadth, not depth, and there are tons of skills to spread points into anyway.
