I think the only likely TV show would be yet another reboot, whenever this film franchise has wrapped up.
Nobody would have a motive to do that. Whatever the new reboot would be, it hasn't proven itself to be a money-maker by being a big-budget summer blockbuster. So there's no motive for the bean-counters to take a risk on it, vs. the infinite number of other ideas they could take a risk on instead.
The one massive value of Abram's universe is that it's now a proven money-maker. That is the one and only factor that would motivate a TV show to be made.
If they want to create a whole new cast of characters for a TV show, they've done the legwork so why not?
Creating a new cast of characters
is the legwork. Why create new characters when they already have characters proven to turn a tidy profit?
The legwork I was talking about is the harder thing: to convince the corporate honchos that there's money to be squeezed out of the
Star Trek brand!
Once you've gotten their attention and their quatloos, then you can hire some writers to invent all the characters you like. So yeah, that's the easy part. There are all kinds of out of work writers in Hollywood who are perfectly capable of doing good work. The hard part is getting the money to hire them, and the directors, makeup people etc.
If the CBS brass figured a
Star Trek series was worth investing in, they'd not only bankroll production but also market it sufficiently to draw in at least some of the audience that enjoyed the movie. Give them the same elements - likable characters, nice SFX (by TV standards), gripping, adventurous plotline - and you'd have a decent shot at success.
Looking at the actual characters, Spock is the only one who strikes me as pretty ingenious of a creation, an iconic character you don't see come along every day. The rest are the sorts that any reasonably good writing staff could devise. So you'd have a cast of characters that are on par with the TOS crew, minus a really great Spock type. Oh well, could be worse.
And of course - casting would make or break the show.
