What I would have loved to see was one where Voyager got really low on resources. Like, the replicator is broken, the holodeck is nonfunctional, the crew is deprived of basic creature comforts for several episodes in a row. Quark's theory on humanity being put into practice with Voyager, to see if they can still hold onto their Federation morality when their bellies aren't full and sonic showers aren't working.
Yeah, as preachy as Janeway got during Equinox... I could actually see her doing the exact same thing as Ransom did in his shoes.
