Looking at the last posts from amazon77 and katank the solution is to bump up the stats for Carthage and the Seleucids. I've added 3 to the Iberians' defence and 2 to the Libyan Spearmen's attack, with 2 added to the Levy Pikemen's defence as they're clearly wearing helmets. Egypt now has a starting treasury of 7,000 denarii, but the Seleucids now have 10,000 and Carthage a whopping 15,000. Carthage can now recruit slingers in practice ranges (like Egypt), with archers and ballistas available in archery ranges. The Seleucids also have ballistas and a larger population. I only finished the mods today, so I'm itching to try them out!
