There's nothing to stop such a massive leap forward, but I don't see any reason why it's desirable to force the novels' story progress to jump forward 6 years just to conform to one comic-book miniseries. Particularly given that ST screenwriter Roberto Orci has repeatedly stated that Countdown
isn't canonical, even though he's credited as its co-plotter. (He reiterated that statement just a day or two ago in his TrekMovie.com Q&A thread, in response to questions about inconsistencies between Countdown
and the film with regard to the Narada
's destructive power and the apparent contradiction over whether Spock knew Nero beforehand.) The novels have their own stories to tell, and they should tell those stories at the pace that makes the most sense.
