There could be a space for 2 civs with Maritime focus. Probably, Phoenicia could be less focused on trade, rivers and resources and more on science and diplomacy. It's possible to distinguish them enough based on this.It seems that Aksum now almost entirely occupies the "Ancient Maritime Trader Civ" niche - and I wonder what the design of Phoenicia/Carthage would be down the road.
(Arguably, Carthage was not that maritime-heavy IRL, and a difference can be made there.)
