1. I thought IQ/g was always known to be an oversimplification (even the guy that invented it noted this)? 2. As this article points out, almost half of the performance of the various subsystems does seem to have a common source. So getting rid of IQ/g completely wouldn't make sense. Now, pointing out specifically which other factors are most relevant for specific tasks would be useful (especially for things that require reading emotions, since that's least correlated). Finding which factors are least correlated is useful (so you know what's most important to check tasks for).
