OKay, this is a players discussion for players.
Yeah, you GM's can contribute if you want but this topic is geared toward players.
So the root question is, "How do you get rid of the Hutts?"
Our group is getting their feet beneath them and we just put together a pretty well upgraded YT-2400 geared with combat in mind. (We have a crew/passengers of 8 so smaller ships weren't an option).
And in addition to being bad sophonts, a couple of our players are strongly desirous to knock off as many Hutts as possible before we are hunted down an killed mercilessly.
As far as liabilities go, Hutts, are wealthy, long lived, durable, ruthless, well protected, and they mutually support one another (mostly).
So frontal assaults aren't going to work.
Setting up internecine conflicts are a no-go too. Hutts tend to not interfere with each other too much. Even if they hate each other they're going to live and let live.
RotJ showed us a well coordinated long term take down of Jabba, but I'm pretty sure our group wouldn't be able to coordinate anything that elaborate. (Maybe your group could).
The best idea I can come up with is to pick one Hutt, recon and research their operations and then move subtlety to start disrupting and dismantling their primary operations.
I'm guessing the next phase would be to dance around with a couple of bounty hunters.
Eventually, once weakened, we go in and slice the Hutt's computers and extract incriminating data so that we can start messing with related Hutts.
Anyrate, there's got to be more than one way to "Salt a Slug" and I'm all eyes.
