It’s been demonstrated in the Chinese review that, since the head sits on a double ball joint, it has some sideways tilt- but it appears impossible to ever have a flush connection like your edit since the head section is wider all around than the neck specifically to allow for more articulation.
Only negative for me is the cape length. Unfortunately, switching the the HT would be inadequate since it lacks the inner lining and has the hideous, exposed folded stitching, which would be visible from a frontal view.
Might be the one thing I’d consider upgrading if anyone can come up with a perfect replacement.
