Actually, I had this idea years slightly before the reboot aired on a Star-Trek Forum that had lots of 3D graphic artists: I figured the reboot was going to suck because some of the graphics I saw weren't actually from the show, others were and looked like they decided to stick joysticks everywhere for no reasons, and put fancy cool displays that had no real purpose.
More or less, I thought they were just going to massacre everything the show was about, and since I didn't understand at first that they were going to start the story off with a time-warp; I figured they were going to go from Star Trek Enterprise (which I thought basically threw a monkey-wrench into the timeline with all the time-warp stories) and just zip ahead like 100 years with a revamped timeline that would probably have nothing to do with the original story.
Since the forum had a lot of 3D graphic artists on it, I half jokingly proposed a fan-made reboot which involved getting a bunch of 3D graphics artists together and making a movie using 3D animation: There was a movie called Final Fantasy that used 3D characters instead of actors and it made a strong impression on me (admittedly I don't remember what the movie was about, but I remember the graphics) and I've seen some graphic artists on the forum who did some seriously good work with 3D human models.
The idea basically involved restarting the timeline where The Motion Picture started, but with a different plot, and took a casting concept based on Law and Order (that being that the story shouldn't hinge on a character -- but on the storyline: In star trek, it's exploring strange new worlds and boldly going where no one has gone before and stuff; in Law & Order it's about the criminal justice system in NY being represented by the Police and Prosecutors and their stories followed by a double gong meant to vaguely sound like somebody banging a gavel): I figured Captain Decker could stay, Chekov was young, and the rest could just end up new people and stuff.
The major problem had to do with the fact that rendering at that detail and making all the animation and frames for a movie would require mucho processing power and would require the construction of a rendering farm: I then thought of using a game engine like the CryEngine instead for the scenes with the "actors", and just 3D graphics otherwise.
When I found out the story was going to be based around a time-warp, I was a little more open minded, but once I saw the movie: Well it did massacre the plot and it didn't even have any real "science" in the whole science-fiction thing; the second one I saw because sometimes a story can be so bad, it's good.
BTW: Yes I know about the Stephen Collins thing -- that wasn't known to the public in 2008-9)
