Just want to ask a question about HORCRUXES.....

Well, I just want to ask a question about HORCRUXES??? My question is:
In book 2 (Chamber Of Secrets), just in case the soul encased in Riddle's Diary (which is we know a Horcrux) managed to "rise again" (when he sucks the life out of GINNY), what would happen??? I mean, what would happen to the REAL VOLDEMORT??? Would the VOLDEMORT who will "rise again" would be the same Voldemort or a different one? (A sixteen (or seventeen)-year old Voldemort?) Would that be possible? 

Is there a way we can ask this out to JK Rowling?
