Reading comments about FarScape makes me think of another way the series could've gone, that would be a major departure from what we got. Instead of a ship of people being abducted, what about just individuals from across the galaxy being transported the Array where the Caretaker is experimenting on them, looking for someone who could become his successor to look after the Ocampa, but with his time running short and a station that hasn't been as well maintained as it should've been then he can't complete his task. As such his equipment releases the captives who find themselves stuck with one another, but as the Caretaker's death gets steadily closer he sends out the remaining aliens on a ship that was integrated into the Array, so this small group must figure out where they are, how to work the ship, and how to work together in order to get everyone back home.
This way you could have a very diverse cast, mixing characters from species we know (such as a Romulan Centurion and a Cardassian Glinn) in with races no one has ever seen before, on a setting that breaks from the traditional look of Starfleet, so that the crew can have some good conflict amongst themselves with less uniformity, whilst there would also be the chance to explore the ship as much as the space they're in.
