Three or four mini-series, or TV movies or straight-to vid productions. With the understanding that the one that got the most favorable reception could be the basis for a new series. I would be open as to subject/timeframe but always love to see "lost era" projects.
1. Between now and Cochrane.
2. Between Cochrane and Ent.
3. Between Ent and TOS.
4. Between TOS Movie era and TNG
5. Post Nemesis. (Although quite well covered in Lit.)
I would love to see option #4. Wrath of Khan uniforms are awesome
And the Excelsior/Ambassador class ships are great looking
The Lost Era books are filling in this time period somewhat. But there is more back story for a TV show to develop.
