Well, some stuff may be included, it will depend on the team but others won't because they are just too different.
For example, my Punic War scripts spawns 2 full Roman armies near Messana and one of the spawns assaults the city right away.
On the next turn, another Roman army appears in Sicily as well as a weaker rebel army composed of regional greek units and mercenaries (allies of Rome in Sicily).
Next turn, another strong Roman army spawns in Sicily as well as ships.
After that, no more Roman armies spawn until the Xantippos event where a very strong but not numerous Roman army spawns in Africa as well as an highly experience fleet and another Roman army in Sicily. On this spawns, the troops are all very experienced (the result of years of war) with many of them having gold and silver chevrons.
Finally, there is one last spawn after that, a Roman attack at Lilubim to try to win the war, where a strong Roman army with artillery will assault the city (and there are very high chances that you will loose the battle), there is also another Roman army that spawns nearby but doesn't support that army, and a fleet also appears near Lilubim.
So, as you can see, without taking into consideration the fleets, there are 9 army spawns in Sicily and Africa during the Punic War compared with the only 1 that is the current build.
This is a highly scripted war and many wouldn't like it. But I tested it and it is really fun, the war for Sicily becomes a real pain where you have to defeat strong Roman armies and spend a good amount of time there fighting Romans and getting your armies highly experienced which will help a lot during the Mercenary War.
