If their intention is to make the companions more likeable through changing dialogue, then they should do so by having the characters develop and dialogue change based on action and inaction. By this I mean they could simply keep both sets of dialogue, but the companions react differently based on how quests are completed or approval.
They could be miserable sods like before or more tolerable depending on character development. I mean, IRL you're not going to behave like Lae'zel or some of the others did unless you've got a developmental syndrome like Asperger's or something. You'd actually pick up on social cues and behave appropriately whether or not you entirely agree with situation whether it be out of companionship or simply necessity to survive.
If they could add some companions that aren't banging goddesses, vampires, werewolves, princes, inhabited by demons, immortals from an extinct race etc., etc., and are actually relatable or more normal then that'd be great to. I'm sure when the ship was flying and zapping people off of the street they got some normal people too. *shrugs*

A lot of the problems are baked in, but some reactivity would help.
Hopefully it's a placeholder. It would be nice/ effortless/ helpful if Larian mentioned that, but they are about as reactive as their characters when it comes to feedback. "I'm not going to tell you because I'm mysterious and I have a dark secret and I also have layers... No I can't tell you why we only respond once a month. By the way, did you know X% of players never made it to the goblin village because they got bored?"
God, now it's been mentioned, the asperger's diagnosis is difficult to let go of.
