I wouldn't even consider conventional chemical rockets for such a rendez-vous. There already are plenty of other options available: ion thrusters, or the new plasma thruster NASA is currently working on, which is very promising, or a laser sail... even that dubious emDrive if it proves working. The tricky part is really what to do on arrival if we don't want to just pass by it at an enormous speed.
