What would be the difference except the number of rows?
I dont know if its possible but a system of ships and upgrades similar to EU4 would be more than decent.
Actually we are in the era of the breakthrough in ancient naval warfare since we have this new models of ships. Pliny the elder reports that Aristotle ascribed the invention of the quadrireme (Latin:
quadriremis; Greek: τετρήρης,
tetrērēs) to the Carthaginians. Although the exact date is unknown, it is most likely the type was developed in the latter half of the 4th century BC. Their first attested appearance is at the siege of Tyre by Alexander the great in 332 BC, and a few years later, they appear in the surviving naval lists of Athens. In the period after Alexander's death (323 BC), the quadrireme proved very popular: the Athenians made plans to build 200 of these ships, and 90 out of 240 ships of the fleet of Antigonus (306–301 BC) were "fours". Subsequently, the quadrireme was favoured as the main warship of the Rhodian navy, the sole professional naval force in the East med.
Last but not least, the first Punic war it was mostly a naval warfare that Romans had to adapt(corvus etc) to break the Carthaginian power.
