Here's my non-barbie approach:
The nerdiest glasses I can find (from SORGO, well worth a visit if not only to get inspo from the portraits hanging on the wall there ), add-on ears from l'etre angled a bit out and maybe a bit oversized, assymetric features as per Orwar (even on the add on ears...) and some of the stuff from Izzie's lie Trophy/Anna mentioned together with the goofiest facial animations from the Catwa HUD. Skin is from Pink Fuel btw. Oh, and hair from Dura!
Also cleans up quite nicely when going a bit easier on the ears and adding some makeup I think
