as i just began an advanced campaign with Koinon Hellenon (didnt care the first time about guard mode/on off and using the knowledge of recruitment viewer and http://europabarbarorum.heimstatt.net/ for alternative units) after the hints from FriendlyFire actually i see no problem with it.
@fomalhaut: just use the heimstatt data together with the data you get from the rec.viewer - the viewer tell you which MIC type (and hence which government) you need for the units in the mentioned provinces. (with checked "Detailed Info" in the province data window)
