[Help!] Scripting the appearance of Hannibal's army

[QuintusSertorius]

This is a follow on from the thread in the general forum. In a nutshell I need some scripting and I'm clueless as to how you do it without wrecking the game. The limits of my modding skills are minor tinkering with the EDU and strat.txt.

Here's the situation. In 216BC I'm going to gift Capua to Qarthadast (roleplaying, it's after losing Cannae). I want Hannibal's stack to appear in Campania when this happens. I'm hoping that having some actual Qarthadastim territory to defend will prevent him trying to wander off to Spain.

What would also be nice to have is some "regeneration" of that stack in the form of Italians (Samnites, Bruttians, Lucanians). Possibly an army of Italians fighting for Qarthadast at various points too, to give me some battles I can actually win.

I like the composition from this post to start:

The army that Hannibal used for his campaign in Italy after recruiting some Gallic mercenaries in the north of Italy. A lot of soldiers from different nations.
10/ 12000 Africans (4000 light)
7/8000 Spania (4000 light)
10/15000 Celts
4000 Numidian cavalry
4000 Celtic heavy cavaly
2000 Spanish heavy cavalry

with EB units

1 General
Infantry
1 unit of Balearic light infantry
1 unit of Balearic slingers
1 unit of Iberian caetrati
1 unit of Iberian loricati scutari
2 units of Numidian skirmishers
2 unit of Gaesatae
3 units of Geroas
2 units of Aanatim Aloopim (Elite African pikemen)
1 unit of Dorkim Aloopim (Elite African swordsmen)
Cavalry
2 units of Numidian cavalry
2 units of Brhentin (Gallic noble cavalry)
1 unit of Iberi Lanceari

The Africans in particular should be in the 5-7 experience range, the Iberians in the 2-4 range. That should give them some survivability. Then hopefully the Italians appearing will reinforce the Gallic losses.

What also needs to happen is that on a specific cue (either date or taking a settlement) that army is teleported to Africa to defend the homeland.

As a nice to have, Hasdrubal's army in Spain:

Second Punic War – Hispania

Based on the army of Hasdrubal Gisgo and Magon Barca at the battle of Ilipa
50/70000 infantry
4000 cavalry
32 elephants

with EB units

1 General
Cavalry
1 unit of Numidian cavalry
1 unit of Iberi cavalry (lanceari, cursi, equites caetrati)
2 units of elephants
Infantry
1 units of Misteret Izrahim Tsarim (Phoenician citizen phalanx)
1 units of Dorkim Lubaim-Ponnim Mesoarianim (Liby-Phoenician heavy infantry)
2 units of Aanatim Lubim (Lybian spearmen)
4 units of Aanatim Aloopim (Elite African pikemen)
4 units of Iberi infantry
1 unit of Balearic light infantry
1 unit of Balearic slingers
1 unit of Numidian skirmishers

They don't need any regenerating units or anything, just to appear around 209BC.

Possibly some other reinforcements like those landed in Sicily, the ones that nearly got through to Tarentum and those in 215BC and 207BC (the latter resulting in Metaurus).

Alternatively, if it can be done via console command, I'd be appreciative of that.

Any help welcome!
