I think the OP needs to define what having the prime timeline "back" would entail. Would it mean tossing out the JJ stuff? Having both coexist? Wrapping up the JJ stuff properly but then switching back to prime for whatever the next live action Trek project is? Etc.
Do I love the prime universe? Sure. But I also love the JJ stuff and wouldn't want to sacrifice it. I'd be cool with both running alongside each other, but I don't think that would work for mainstream audiences or for Paramount. And as others have said, there's no shortage of comics/games/books set in the Prime timeline.
