meh_cd - I think they should have a helmet - maybe the type used for heavy peltasts and regular hoplites. The colour scheme should match hoplites and armoured hoplites - unless you can come up with something that (1) fits with the vanilla style but (2) also looks distinctively Athenian.
Leonidas123 - The Skiritai sound interesting. I will have to think about what sort of unit would be suitable.
