Many years ago I was able to book ONT-MSP-AMS-NBO and return WBC for base miles, but it took a lot of work.
Several people have suggested alternative routings using KQ through London, etc. I'd also check, although it will probably be a long shot on DL to another African destination (JNB) and the KQ to NBO.
