>>5512471>Also, since I've never mixed two lines, will I be lucky in general (skin tone, joints) or I'm going to face bad looking results without some kind of further mod?The main difference is that QB's head joints are at the base of the neck, while figma's are athe top of the neck, so a simple headswap won't work.
There are two posibilities:
1- get a figma eva girl, they have a special neck part you can use, but it will look a tad too thin
2- do like pic related and use blutack attach the figma head; just be aware that out of all the QBs I have, Melona's the only one whose neck piece got separated like that (not broken) so I don't know if it works with other QB girls.
