imomodoll head on obitsu 40

Hi! I recently bought a 1/4 imomodoll head and was thinking about putting it into a parabox 40 since i'm not too fond of the imomodolls bodies and the joint issues that they tend to have. Was wondering if anyone has done this before and how to go about it?

I don't own a Parabox 40, but I do have a 1/4 Imomodoll head as well as a Parabox 50, and I think from looking at pictures and my own dolls the neckhole of the head might need to be modded some to be wider. Parabox and Obitsu use a system where the top of the peg "grabs" the vinyl from inside, which means you want the hole to generally be just slightly too small for the peg and use a hairdryer or other heat to temporarily widen it. At least, that's from my experience.
