IMO there is simply no Trek movie idea imaginable that would be both interesting and true Trek. The pouring over continuity and characters is missing the whole point of Trek. Star Trek was about exploration and the unkown, along with progressive social values filtered through the experiences of loveable pop-culture archetypal characters, providing an television medium for science fiction templated story telling. With 726 episodes and 10 movies of Star Trek already having been produced and shown to the public, along with hundreds of other sci-fi shows and movies, there is simply nothing left to tell that is new. Star Trek's purpose is gone.
I'll tell you where I disagree with that.
Another big piece of Trek (particularly in TOS), was taking on social and political issues of the day, but doing it in a sufficiently removed (SF) setting that people's knee-jerk emotional responses could be minimized to plant a seed of more rational thought (al least, that's the idea). Whether it was racism, sexism, superpowers using underdeveloped client states to fight wars by proxy, increasing mechinization of warfare, or the generation gap ...... Trek took them all on (and yes, generally from a liberal leaning POV).
As long as there are social and political issues in the real world, there will be fodder for Trek stories. Of course, the producers, writers, and distributors (whether movie distributors or TV networks) have to be willing to take the heat that goes along with that.
