Ideas for Series VI
A 25th Century based Trek Series involving a Timeship pursuing another Timeship which alters the past from TOS on up! Which could open up possibilities of alternate realities AND exploration of worlds mentioned
but not shown.
A late 23rd century era (post Generations) based Series on a Excelsior-class starship exploring new territories, similar to TOS. Maybe Enterprise-B based!
Late 24th Century era (post Nemesis) based Series on a starship that docks with a space station, a combo of DS9 and TNG type of stories.
The third option seems to be the best of them all to me.
