Merge a body part for a demon character with a belly mouth

fichtl-stefan

Hello I want to create some kind of demon character in daz3d. The character should have a mouth in the stomach area. It would be best if the mouth was movable (rigged) I tried hiding all body parts of a Genesis 8 character (except the mouth) and just moving it to another character's abdominal region. Unfortunately, I don't like the result at all. my question is now what would you do? Create a morph with zbrush so that the belly matches the mouth as well. or is it possible to create a geograft abdomen with the mouth e.g. in the hexagon. Unfortunately, I'm still quite new to the subject of Blender and Zbrush and am currently trying to acquire knowledge via tutorials. I haven't found anything related to the topic yet as I don't want to create a complete mouth from scratch (at least for now). I've attached an image of what it should look like

A GeoGraft would be the only way to do something like that, but having it span multiple body parts would make it very hard to do.
