That's an interesting strategy here, never payed that much attention to skirmish mode since my units always get caught... There's a slight problem though, needing 4 units to obliterate 1 or 2 is fine, but what are you going to do to take care of the rest of the army in the meanwhile? I suppose you'd need plenty of space for both the skirmishing and the trap too. Perhaps you could use some light javcav to greater effect for the luring purpose: you can keep them just out of the Gaesatae range, but they'll tempt the fanatics into a vain charge anyway (being cavalry after all). Especially Hippakontistai, they have a decent secondary attack as well.
