I did not notice that myself but daz really has some problems with lip thickness and it is not limited to G3, G8 have similar problems so your idea to reduce thickness using extra morph is worth trying. It will be useful for me as well.

But another problem is mouth and lip shape, as they are not only to thick but also the center is sticking out too much while corners are pushed in. When the mouth opens it looks pretty unnatural, since wide open mouth is supposed to be very smooth
for example in this picture >>28533 , mouth is very irregular for some reason and looks like it is totally loose
It is unclear why many of your girls have kinda "pouty" lips like that that do not open properly
