To unpbo or simply look inside pbo files Pbox seems to me the best choice. The female civilians came with the Resistance Addonpack by BIS. So those girls should be inside the o.pbo.
There was a thread on the official BIS Boards some times ago, which should some female models made from scratch. But these were, eh how can I say, formed and model too realistic. So I don't think the fit in a kids mod.

Yep, typo it's "Bundeswehr"
P.S. Ah, I forgot one thing: There was some kind of japanese action/manga figure mod (with a female hero) a year or so ago. When I'm back home from the office I can search for it Spoons.
