Well, people datamined that Jaheira is/was married to Halsin, so i can only imagine what's in store for Minsc. Maybe that he never really cared for Dynaheir, who knows.
That's an interesting way of looking at it. It's been about a hundered years since Khalid's death and in BG2 she is a romance option for PC. Why wouldn't she find another mate by now? That's quite a change in taste though. I also felt a great disturbance, as if millions of thirsty Tavs suddenly cried out in terror.
I don't remember there being any romance between Minsc and Dynaheir, unless his right of passage job as a bodyguards comes with unmentioned benefits.
Could have gone without being reminded of people's thirstiness for body-type 2.
But anyway, frankly it's about respect. Even if it was their story and their character, which they aren't, i don't see what anything of the like would grant, other than sourness, to all those who've grown attached to that story and that character for the past 20 years.
As for Minsc, i was being coy. I'm sure they can butcher him without some deep digging into his backstory.
