This mod uses a model from Yuria's "Neck Connector Fix [DT]" (TBSE neck connector for tall males).

Something of a proof of concept thing, made this for convenience for myself and figured I'd put it out for people to check how it could be replicated. Should be fairly easy to understand and reverse looking at the files, but my socials are open to questions. I'd wager this kind of mod would go well with certain types of accessories or prosthetics or permanent body modifications that involve a separate mesh and are meant to be permanent on your character.
Anything using attributes is likely to not apply them correctly, the same goes with shapekeys.
This puts the spikes hair accessories from male Au Ra hair 1 and joins them with your body's neck connector (will require TBSE to display the connector piece), so it should work with any face/sculpt, hair, or gear combination. Raen and Xaela male.
