While theoretically possible, availabilty is difficult and the mileage would be a lot more. The routing would need a 2nd ow airline in addition to CX to be a valid ow award. And you must be careful about the schedules as a transit could be considered a stopover thereby making the mileage accounting much higher. Can't do it as an all partners award since routing to Africa must go via the Atlantic. Also, mid-december is prime travel time such that any awards for 1, let alone 2, will be very difficult.
