Comparing what Ghana hosted at the African Games and what was on the program at the 2022 Commonwealth Games, we are missing cycling (mountain and track), diving, gymnastics (artistic and rhythmic), lawn bowls, netball, powerlifting and squash.
We may be able to fit gymnastics, netball, powerlifting and squash in venues which had events not part of the Commonwealth Games.
It looks like Ghana has a pre-existing mountain bike course and possibly a place to host lawn bowls. I'm unable to tell if the swimming venue also has diving boards so that and track cycling may have to dropped from the program or given to a different host.
