ixBrowser have a well documented API and I myself use it in BAS but only for creating new profiles, doing batch updates or loading cookies into the profiles. If you want to completely control the browser from BAS I don't think it's possible or at least you don't need BAS for it.
I need a BAS expert to help me editting my BAS made bot
