We're all familiar with the Gallic Celtic influence on Hellenistic Greeks and other peoples of the Eastern Mediterranean with the adoption of the thureos shield, helmet types, and chain mail armor for the torso. Everyone here should also be familiar with the Hellenistic Greek influence on the customs and fighting traditions of West Asiatic and North African natives, such as organizing ethnic Persians and Egyptians into companies of phalanx pikemen (phalangitai). There is also the Roman legionaries' alleged influence on the equipment and fighting styles of West Asiatic states like Pontus (although these were seemingly borrowed firstly from Greek thorakitai and Galatian Celtic warriors and were developed independently from the Roman maniple system and later cohorts).
However, did Hellenistic states ever organize Thracians and Illyrians from the Balkans into units of sarissa-wielding Macedonian-style phalanx pikemen? The game hints at this with the "sibinanai" (Illyrian "peltophoroi" infantry), who wield much shorter pikes than the sarissa wielded by Macedonian phalanx troops. The Illyrians and Thracians were both significantly Hellenized, a process that began even before the Hellenistic period during Archaic and Classical period waves of colonization across the Mediterranean and Black Sea basins. Illyrian and Thracian equipment and armor already had a lot of overlap with Greek designs, while the Thracians were equally influenced by the Celtic fighting styles and equipment, manifested in units like the katoikoi swordsmen in EBII.
Obviously people of full or partial Illyrian or Thracian descent were recruited into the armies of Hellenistic states and mixed with people of other ethnic groups and regions, and entire allied auxiliary units consisting of Illyrians or Thracians existed. My question is more narrow and specific: were there entire companies of phalanx pike units composed of either Illyrians or Thracians? By that I mean like the Persians who were levied and trained by Alexander the Great or the later Ptolemaic Egyptian machimoi.
