I'd like to see the Sidewinder get a chance to do what it was built for - running a blockade.
The idea would be that crew Kiro, upon either being asked about Zhen Shei (where she talks about how Steele stole the Sidewinder) or upon being asked about piracy, would say
"Doll, you have this great ship that was built for running blockades - how about we use it? I know of a planet that is being blockaded - they need food and medical supplies, but another star system is trying to squeeze them out. (if Steele is kind) I know you love to help people out, and (endif) we could make a LOT of money on this run."
If the player accepts, they get a mini-quest where they
A) Go to some planet to pick up food and medicine (either a new planet, or perhaps Mhen'ga) (this could also be an opportunity for Bianca to come along for medical help).
B) get a fake transponder so the ship isn't tracable to SteeleTech (maybe a miniquest on Zhen Shi)
C) Go through the warp gate and immediately be attacked by the blockading forces. The player is given a chance to try to BS their way through (which fails), fight there way through (which should be a damn-near impossible to win fight), or run the blockade (start fighting, then select the "Run" option, which is the "right" answer.
D) Deliver the supplies and possibly take on other cargo (some sort of valuable tech, or minerals, or ???). If Bianca is on the trip this might allow for some interaction as she treats the locals.
E) Try to get back home. Running isn't an option: you have to go through the Gate and it's blockaded. Options are fight (and get your ass kicked), or (the right answer) wait until another ship is cleared through the gate, then run like hell to tailgate them through. This might lead to either dropping the characters off in a random star system in the game, or having them get dropped into a new star system, either a playable system or a short stop before turning around and going through the gate back to one of the standard systems.
