Maybe you can use this  
[Curved2Geometry - a twofold curved geometry](https://discourse.threejs.org/t/curved2geometry-a-twofold-curved-geometry/25580)  
or this  
[Multi Form Geometry](https://discourse.threejs.org/t/multi-form-geometry/36839)  
or body parts of  
[Pino - a procedurally generated and moved skeleton figure](https://discourse.threejs.org/t/pino-a-procedurally-generated-and-moved-skeleton-figure/36184)

Less complex is  
[How to update tubeGeometry geometry based in lineCurve modifications? - #14 by hofk](https://discourse.threejs.org/t/how-to-update-tubegeometry-geometry-based-in-linecurve-modifications/40854/14) =\> [DynamicTubeGeometryCaps](https://hofk.de/main/discourse.threejs/2022/DynamicTubeGeometry/DynamicTubeGeometryCaps.html)

There line 251  
`v3a.multiplyScalar( g.radius );`

You can vary the radius. You don’t have to move the geometry either.
