I'm on board with more Insight checks during dialogue, especially as a way to get an idea about the person you are talking to (and how they may react to certain skill checks). (eg: if a character already looks angry, you'll probably have a hard time with intimidation)
Larian have already seamlessly integrated them in several cutscenes and dialogues.
Story Time: During the first 2-3 days of EA everyone was bashing Astarion for attacking their party. I was so confused!!
Ok, so the guy was a bit sketchy but why was everyone harping about him trying to kill them... He'd always just brandished a knife on my character (pretty half-heartedly too) so of course, I was reasonably polite to him and we got off to a pretty good start. Then on my third run, I noticed the roll for Wisdom/Insight had succeeded and my character had noticed him creeping close. This completely changed the flow of the cutscene but it had been done in such a non-intrusive way, that for my first two runs, I'd just taken it as part of the storytelling.
