Hello
my plugin NAutilus allows to flow along mesh, it can transform slopes to vector and rotate them.
So you will have a vector field. Then you can use my tool to flow points along vector field. ANd if field is too dense it is possible to suppress some curves.
The only drawback here is that it doesn’t work on big mesh. So I had to scale it to 1/1000.
here along slope
45°
70°

For the twist I have a component that gives vector for a given slope. But as in your geometry slopes are everywhere it doesn’t give what you want.
The second way is to tween 2 vectors field using a scalar field representing a distance to the curves you choose. You just have to generate a value [0 1] on each point of the mesh, then
Vector = Vector (x°) * alpha + Vector (0°)*(1-alpha)
Small distance from the curves and sharp change
Less sharp
You can rely on slope
or not
