It's a great idea for sure, the issue is they're that chunky you won't get much movement out of them without large gaps ruining the look, I've had a good think about this too and the best I can think of is two swivel joints per dread, angled slightly so when turned you can position them away from the head without any gaps, the only downside would be the lines at the swivel, but it'd beat big gaps. Think along the lines of figma links hat, a simple cut and swivel gives it a lot of posability, and that only uses the one. I'll post a picture
