Alright, I haven’t written anything yet. Just want to throw out some concepts.
I was thinking about placing the crew in another 'verse. And it suddenly hits me, transplant the firefly crew to the Star Trek universe. Have the Captain and Zoe to be the few Maquis that survived the brutal Dominion attack.
The former Maquis Mal bought a ship and started running cargo at the far edges of the Federation. While they hate the Cardassians, they despise the hypocritical Federation even more, for hunting them down and then sitting by when the Dominion slaughtered them.
The crew does their best to avoid Federation and the Federation’s attempt to make people better. Doing jobs as they come, legal or illegal alike.
The crew can run into people from DS9 (like Kasidy Yates) and former Maquis crew from Voyager. And even run into Section 31 because sometimes Section 31 needs jobs done by low profile people.
Serenity in the Trek 'Verse. How does that sound?
