A concept like conversation battles was never going to work for a game like this, it's at odds with what the devs want to do.
'For a game like this' or 'for this game'? Because for a porn games it works. Mentioned million times Lilith Throne sex system is a 'conversation battle' on some level. Even just for ordinary games it works, as were proved by all text adventures from 80s.
Even something as simple as the Master dialogue at the end of Fallout 1 was set up earlier and required you to go out of your way to do. It rewarded players who explored and got invested in the world.
Could work without even without exploration, if game tells you current mood/reaction of a NPC on players shit.
Player: *casually approach NPC*
Player: 'Hey, you heard?? John died from suconda?'
NPC: *mourning face* 'OH NO....' *confused face* 'Whats succonda?'
Player: 'SUCCONDEEZNUTS!!!! GOT`EM, HA!!!!!'
NPC: *facepalms, looks like you now unable to interact with this NPC*
There are should be battle like system for dialogues, which would track whats going on, to direct conversation to one of the possible outcomes. Tobsed battle, which was the beginning of this discussion, have only two outcomes,
good and
bad. There are no 'liberation of female salamander' or 'liberation of male salamander' or 'obtaining skill-steal only', only everything or nothing.
*obligatory 'why tobs is a writer?' question*
