If you could replace any one of the actor-characters from Star Trek; TNG with an actor-character from another Star Trek series, who would you replace and who would you replace them with?

I would replace Frakes / Riker with Farrell / Jadzia Dax, and she would be the new Commander.

May I ask Why?

I'd make Troi take Kirk's place. Now THAT would be interesting.

Neelix instead of Picard, just for fun

Spock instead of Data or Tuvok instead of Spock--wait, there would be no difference!

Does anyone see a pattern in most of the star trek shows? That there is usually a roboticky person as part of the bridge crew?

Yeah, someone who always sees logic. Maybe its standard for a ship to have one logical thinking officer ie Odo, Data, Spock, Tuvok

replace worf with neelix
