Should there be an episode where Harry Kim travels back in time and joins them?
I think there should. What could happen is that Wesley Crusher steps out of his Traveller persona and bumps into Tom Paris on Voyager who he thinks is Nicholas Locarno who he went to Starfleet Academy with. Turns out Tom was (Or is depending upon how you look at it) and fabricated a really elaborate hoax which he could never fully admit to which would have jeopardised his father's career and legacy within Starfleet.
Anyways they all travel back in time to find Data's head which Samuel Clemens is the guardian of until his future offspring can put back to make sure the timeline isn't messed with (A descendant of his from Vhnori called Neria also goes back in time and meets another cousin of his called Radue who is an Aldean).
It all gets a bit mixed up but Bones eventually bumps into them and then they all notice there isn't any women in this episode and so they get cancelled due to hatred from the Internet from people who have no idea who any of these characters are.
This should be the pilot episode in my opinion. Maybe chuck a bit of T'Pol in for good measure to make it at least watchable for us who actually cared about Trek pre-Abrams.
All further characters and story arcs will be considered for inclusion should you wish to share them.
