Considering doing a Carthage TL.
I have two POD's I am thinking about.
1st: Alexander the Great dies, Macedonia collapses into civil war over who is the heir, Persia takes control.
2nd: Agathocles' expedition to Carthage fails, and Hamilcar sieges Syracuse, Agathocles is killed, and Sicily is secured by Carthage.
Maybe the TL can use both POD's in a way.
