Five years may just be long enough for Dick to quit, Jason to become Robin, Jason to die and then Tim to become Robin, but Dick wouldn't have quit until he was at least 16 (he was 17 in the comics when he became Nightwing and he is 18 in YJ now) and Jason's death made Batman reluctant to take on a new Robin (Tim had to pretty much blackmail his way into the role) and I just don't think 5 years is long enough for that.
