Great news! As long as it does happen I can certainly wait for it!! Text box to existing conversation UI window sounds both the best case and the desirable one(understandable). Looks like something a mod would do. The pic you display is a new one with different background and suffice to say they had limited resources for new char portraits(mainly the workers in Microforte I think) back then. Do you have Redux? It changes so many things it might be a candidate for this.
