Current run is fine, and rebooting is anathema.
That said, I'm all for new creative teams and fresh starts when something isn't working. Give it to some capable writer and artist and let them do their things.
I think Steve Orlando is doing some fun things in "Midnighter". He's young, hungry, did a cool coming of age thing in Undertow, and has a passion for DC comics. With the success of Midnighter I wouldn't be at all surprised if they gave him Teen Titans, and I'd be happy to see it.
I'd love to see Ben Caldwell put on the book post-Prez, but I also think Scott Hepburn did a great job on the fill in he did. Generally I'm all for expressive, energetic cartoonists on this kind of book, as I see it driven by the personalities more than the plot.
I think much mileage can still be gotten from a 'trinity' of Tim, Cassie and Kon El, especially as long as they don't have their own solo books (though Tim will be, no doubt, heavily featured in Batman Eternal 2 and Kon seems to be in the offing for a solo coming up). I also think the current 'extra's of Bunker, Raven, etc are cool, as is the 'rival' team. Maybe bring in Klarion, Guardian and Shining Knight full time from Seven Soldiers and see what you end up with.
Big, bright, characterful superhero action/adventure.
I'd also like a little bit weirder, more subversive "Young Justice" title, featuring a cast of 50% new characters and some 3rd tier peeps, maybe the return of Aqualad-as-Kalduur to give it some star power. Plan for 12 issues at most and just build a cool, weird corner of DC Earth.
