I like this option a lot, going to investigate that. We're looking to spend a little time in Madagascar (TNR?) so we can do JFK-JNB and use JNB as a base for both places (and use SA for JNB-TNR). I dislike ADD (the airport is crummy and the Ethiopian flights I've taken ADD-NBO have been crappy...is their business class any good?) and SAA has been nice so far.
