There have been probably a dozens attempts to make a Star Fleet Academy type show, since the late 70s. It would be aimed towards a younger demographic, and more towards women. It would always be a much cheaper show to produce, due to being based on earth, and wouldn't require all the ship sets.
In the books, the Federation is is starting to equip its newest ships with a early Slip Stream. It requires a rare element, they don't have ready access to, and ship size and aerodynamics play a big role. The big E was experimented with the drive, but its a little too big for the tech right now. The voyager series books are now really focused on slip streams. Voyager has been fitted with it, and currently is leading a scout fleet expedition(like 10 ships) back to the Delta quadrant to search for that element. Slip Stream has a large cool down time(5-10 days), so using the drives require a lot of planning, and due to the limited supply of the element, can only be used sparingly.
The USS Aventine, is a brand new test ship, built for Slip Stream, and to be a fast response vessel. It has been featured in the epic Destiny trilogy(Seriously if your a trek fan, READ THIS BOOK!) It features Captain Ezri Dax, and a pretty interesting crew. I would love a series based on that, but it will never happen
