I wouldn't take KH out of there, I'd replace (even though I love them), Baktria for the Bosphorian Kingdom. Similarily, To create the Boii/Early Vandals (forgotten their real name), I'd put Arverni/Aedui up there.
Epieros I would put as Pergemon, and move Saba over to Numidia. To make life more enjoyable, perhaps put a landbridge between England and France? Just my $0.02...
