It may not be clear what OP is trying to do, but I think Yo Dojo has a project with messed up texture and wants to transfer all morphs work to a fresh headshot project.
If that is the case, then Export your current character as OBJ > Nude Character in Bind-Pose >Full Body
Then start a new project and redo the headshot.
Finally use Create > Morph Slider Editor. In Source morph select Current. In Target select OBJ saved from messed up project. Check Adjust Bones to fit Morph.
You'd get a single slider replicating the body you worked on previously.
Another way is to save all the Morphs as AvatarMorphPreset/FullBody. However, I believe it would only be correctly applicable to the Neutral Base.
