You need to find the way to not change topology. Without it will be hard to make procedural setup

Sweep used normals along spline and up vector to orient shapes, by default after dopnet you have orient attribute you need to delete. Use foreach per branch to create shapes and then use it in point deform. In my vol3 tutorial you will find explanation of all aspects of the meshing.

To use curves for deform you need to create geometry using sweep from curves and then plug to point deform.

This picture show nothing. Can you provide scene? Why you use FEM for it, better use wires
