I'm also a fan of the classical period. If you look on the official submod page, you can find a link to a version of Wrath of Sparta that works with DEI. (

It works, but it has its limitations. For example, because there are no reforms, the factions can recruit both Iphikratean Peltasts and reformed peltasts from the start. Athens can recruit Skiritai mercenaries from Athens, too. The Macedonian Wars campaign is fully developed and polished, as you would expect from the DEI team. WOS needs a big update if it is to be truly playable form an historical perspective.
