The week after Self-Inflicted Wounds, Part 2, is called "Different Destinations".
In it, the crew goes back in time to a PK battle between a superior enemy. I think it's the battle between the Nebari and the Zelbinion.
Not only would doing such a thing allow them to bring back Captain Selto Durka for another episode, but it also lets them run into a recently-deposed, recently-tortured, 100-cycle-younger Dominar Rygel XVI.
By the way, a particular line of dialogue from Self-Inflicted Wounds, Part 1, enforces this theory:
RYGEL: You... broke my nose.
CRICHTON: You ain't got a nose, Guido, you got slits.
CRICHTON: Oh! Farscape One to Moya, positive contact with the Docking Web. Hey, nice catch, guys.
RYGEL: I won't forget this Crichton. I swear, you've attacked me for the last time.
CRICHTON: You brought it on yourself, Rugrat.
