It depends how close to hoplite army you want to be
The Hoplite period of Greece ended shortly after the end of the Peloponnesian War, between 400 and 350, when there was an increased reliance on mercenaries, a less hierarchical formation, and less formality in conflict (i.e., more sacking of cities, and noncombatant involvement, less ransom and mercy).
Skip forward to 191 BCE, when the Achaean League incorporates Sparta and Messene, covering the whole region of Achaea (generally the lower half of Greece as we know it today). In Second and First centuries the Achaean army was primarily mercenary light infantry and cavalry. The portion of the army that was conscripted from the citizens of each of the cities mainly consisted of light infantry, which may have been partly javelin or spear throwers, and cavalry. There were also conscripts of heavy infantry called hoplites, but were a small portion of the army and were similar to the Classical hoplites in name only.
Second century Rome is in the middle republic. Around 160 Polybius wrote Histories, part of which details the middle republican army.
The second rank, the Hastati, are ordered to have the complete panoply. This to a Roman means, first, a large shield (scutum), the surface of which is curved outwards, its breadth two and a half feet, its length four feet,—though there is also an extra sized shield in which these measures are increased by a palm's breadth. It consists of two layers of wood fastened together with bull's-hide glue; the outer surface of which is first covered with canvas, then with calf's skin, on the upper and lower edges it is bound with iron to resist the downward strokes of the sword, and the wear of resting upon the ground. Upon it also is fixed an iron boss (umbo), to resist the more formidable blows of stones and pikes, and of heavy missiles generally. With the shield they also carry a sword (gladius） hanging down by their right thigh, which is called a Spanish sword. It has an excellent point, and can deal a formidable blow with either edge, because its blade is stout and unbending. In addition to these they have two pila, a brass helmet, and greaves (ocreae). Some of the pila are thick, some fine. Of the thicker, some are round with the diameter of a palm's length, others are a palm square. The fine pila are like moderate sized hunting spears, and they are carried along with the former sort. The wooden haft of them all is about three cubits long; and the iron head fixed to each half is barbed, and of the same length as the haft. They take extraordinary pains to attach the head to the haft firmly; they make the fastening of the one to the other so secure for use by binding it half way up the wood, and riveting it with a series of clasps, that the iron breaks sooner than this fastening comes loose, although its thickness at the socket and where it is fastened to the wood is a finger and a half's breadth. Besides these each man is decorated with a plume of feathers, with three purple or black feathers standing upright, about a cubit long. The effect of these being placed on the helmet, combined with the rest of the armour, is to give the man the appearance of being twice his real height, and to give him a noble aspect calculated to strike terror into the enemy. The common soldiers also receive a brass plate, a span square, which they put upon their breast and call a breastpiece (pectorale), and so complete their panoply. Those who are rated above a hundred thousand asses, instead of these breastpieces wear, with the rest of their armour, coats of mail (loricae). The Principes and Triarii are armed in the same way as the Hastati, except that instead of pila they carry long spears (hastae).
Rome took Corinth, the last holdout polis of the Achaeans, in 146, effectively taking Greece until Mithridates and the Mithridatic Wars.
Polybius wrote a lot about middle republican armies, and Livy wrote about the Mithridatic Wars in Ad Urbe Condita starting around Book 70.
