Yea, I think a Star Fleet Academy Show could actually do very well on CW, with The General Audience, though I'm not sure how happy The Rabid Trek Fan Base would be with a CW Trek (Being on CW, it probably would be Soapy with lots of Teen/Twenty-something angst, lots of pretty actors playing the roles, backstabbing/Rivalries and probably a fair amount of everyone sleeping with everyone else)
As far as something familiar to attract viewers, I think it's far more likely it would be a Genre Iconic Actor playing a new character in a Mentor position, rather then am Iconic Character returning as a mentor
One Day I hope to be the Man my Cat thinks I am
Where are we going? And why are we in this Handbasket?
