I've said it before, but I'd love to see a "truly new" version of Star Trek...
... on water.
The movie or show would take place on an M-Class planet about Earth's size, and various continents would host the major races, who diverged from a common ancestor before the lands drifted apart: humans, Klingons, Romulans and Vulcans. (Or maybe Vulcans would be a remote part of the human continent.) There'd also be small tribes of the other races.
Anyhow, I see the tech level as being in a Golden Age of Sail state. There'd be naval battles, strange new islands with weird natural phenomena (okay, magic) to explore, etc. The humanist ethos of Trek would be reflected to some degree in the "Federation" fleet, but that empire could also be partly corrupt, and the protagonists of the main ship could then fight for justice inside and outside the Fleet's domains.
Realistically, the only way I see this working financially would be if, after the new moveis run their course, Paramount did a one-off in this style, and sequels if it were popular, much like POTC.
