The concept comes into play in Men of Bronze as the Light Hoplite unit (as well as other reforms and lightening of hoplite gear). The idea that an individual unit would peel off and send runners out to try and ward away or chase down skirmishers, is not really represented though.
In a pinch, it could be a special rule activated with the use of an Arete point, BUT the way the units worked together in the rules all ready; I decided not to include such rules. It would cheapen some of the "combined arms" usage of your own skirmishers and peltasts.
There is still much "work" or research to be down on how Hoplite formations were or were not useful in other types of actions than "pitched battles". There is a lot of detail that seems like it would be only relevant at the smaller scale, skirmish level; with Ekdromo being one of them.
