What should an authentic Hellenistic army look like?

[QuintusSertorius]

2-4 elites on flank (royal guards or makedonian peltasti or w.e)
3-4pezehetairo
1-2 levy (deutoria, etc)
1-2 elite phalanx
2-4 thorikita- Theurophia as flank supporters
3-4 calvalry of medium-> heavy
rest with watever u like

That looks rather elite-heavy to me. Where would they have found so many rare troops?

Exactly. Seeing how most of the Hellenistic states were either in a state of decline (Seleukids) or had too little troops (Ptolemaioi).

Also, keep in mind that you won't send Argyraspides with the son of the nephew of the sister of the son of the cousin of the brother of the King. Argyraspides were elite, so really save them for special persons (the family of the Basileus, the Epistrategos tes Mikras Asias, the Archon tes Aigyptou, the Satrap of Makedonia, etc.).

When campaigning in the east, I advise something like this.

1/2 General
6/7 Pandatapoi Phalangitai
2 Thureophoroi/Shipri Tukul Pezoi
2 Slinger types
2 Archer types
2 Peltast types
2 Light cavalry (preferred javelin-throwing)
2 Prodromoi/Other medium cavalry

Edit: And if you want to REALLY be accurate, I say LOT'S of mercenaries. The AS were in major domestical problems at that time.

So regular phalangites like pezhetairoi or kleruchoi are as "elite" as they should realistically get, unless the general is important?

I don't know about authentic, but this is my setup:

4 Medium Phalanx
2 Elite Phalanx
2 Spearmen for the flanks
3-4 Elite infantry (Agrinian, Royal Guard, Peltastai) for the flanking moves.
2 Skirmisher
2 Ranged (archer, slinger)
3-4 Cavalry (If I got the cash I make them all elite)

A bit elite, but you don't have to retrain so often. Besides, with this you can fight the really big battles.
