I'm duboius about talkign about fan edits in certain places because peopel are concerned about coppyright - I do it for my own entertainment I don't mean infringement; but I've done some:
To The Stars – Using the 09 film and Into Darkness, this attempts to create a canonical origin story for Kirk and Spock. Uses Gabe Koerner’s better Enterprise design
Flight of the Franklin – yes the Enterprise is destroyed but this is the most Star Trek of all three movies, so naturally I turned it into an episode
Star Trek: Phase III – 16 episodes showing the complete adventures of Kirk, Spock, McCoy, Sulu, Uhura and Chekov post-TMP – using footage from movies 1-7, 11-12, TNG, Voyager, Starfleet Academy videogame, Of Gods and Men, New Voyages and Renegades (including Requiem 26B style). Literally the whole story. Every scrap. I’ve edited Excelsior footage from Voyager’s Flashback into Undiscovered Country to expand that adventure.
Of Gods and Men – extended movie edition with the Generations prologue and Sulu on the Excelsior from ‘World Enough and Time’ to show more of the crew post-ST6
Days of Future Past – I’ve blogged about it in the past, but this is the TNG episode Yesterday’s Enterprise using Undiscovered Country/Generations footage to give Kirk a better sendoff. The closest I’ll get to my ideal Star Trek movie MORE:

Legacies – the Bring Back Kirk trailer coupled with Trek 09 and Renegades to create a new TOS finale, set post-Nemesis for the whole crew except Sulu.
Emissary – the DS9 pilot mixed with The Chase and Birthright I to create a full-blown TNG/DS9 crossover - Emissary plays then when the Enterprise goes off we cut to Teh chase footage to show the Enteprirse on another mission nearby. The end shows Data and Bashir's story and Worf on DS9 from Birthright, he doesn't go to find his father. Ends with Sisko and Picard talking. Inspired by the DC/Malibu crossover
The Dominion War – showing the Enterprise-E during the war fighting Jem’Hadar and rescuing Sisko and the Defiant crew
Voyager: The Movie – using footage of the Voyager characters post-Endgame to show their future lives
Inferno – combining the Borg War fan film starring Patrick Stewart with all Good Things and others to give TNG a better send off. Little did I know of course Picard was plotting a comeback! Might remake when we have flashbacks and the Short Trek, make a canon version bridging Nemesis and Picard
Also from Enterprise, DS9 and Voyager I’ve turned several multi part arcs into movies.
My friend has also combined Pegasus and These Are The Voyages footage to make it one story:
