What if Polyperchon(Antipater's initial successor) became regent for Alexander IV and defeated Cassander. I think that this would mean the Argead line holds onto Macedon at least, albeit losing most of the empire. Another possible course is that Polyperchon&Olympias try to conquer the entire empire and are killed, with Alexander IV later being murdered. In such a scenario, Cassander could become Basileus of Macedon( if he's still alive and there would be little real difference from OTL.
