As for me, this route seems good except I will be passing by LHR more than twice?
YUL-LHR-NBO(stop)//JNB-LHR-CAI(stop)-LHR-YUL
On the OneWorld awards, if memory serves me right, you can only transit a city twice - so neither of the above will work - you have three at LHR.
If you just wanted to visit JNB and NBO I would do
SIN-HKG-JNB(all CX)-NBO(BA) // JNB-HKG-SIN and
YUL-LHR-NBO(all BA) // JNB-HKG-JFK (all CX)-YUL(AA)
To bring in CAI, maybe route the returns
JNB-MAD-BCN-CAI (on IB) // CAI-LHR(BA)-SIN (BA or QF)
and
JNB-MAD-BCN-CAI // CAI-LHR-YUL
JNB-MAD is not daily though.
Just stay under 16 segments and remember that for the award distance tiers, what counts is your origin, stops and destination - not how you get from A to B. You are easily meeting the "2 airline other than AA rule". I haven't checked great circle distances to see how much CAI bumps up your total award miles.
