Can I play as Lister, Rimmer, Ktyten, Kotchanski or Cat from the Red Dwarf TV series?

Please no, for the love of God, no!

You can't be any of the main cast, how would that even work? Blue Dwarf is set in the 3 million year gap before Lister is taken out of stasis. So Lister is already on the Blue Dwarf, Rimmer and Kochanski are dead, Cat hasn't been born yet, and Kryten probably hasn't even been made.
