Well… there was/are attempts to recreate Shrinkwarp modifier with geometry nodes to make it more “controllable” maybe to shrink the part closer to teh body more…
like for example:
You could start with this:

the object input to the node is the target mesh
Hi,
I created a new step by step video tutorial about implementing Shrink-wrap in projection mode using Geometry Nodes in Blender 3.1 alpha.
[Shrinkwrap with Blender 3.1 Geometry Nodes - TUTORIAL]
Let me know if you have critiques/suggestions about the technique used, and if you are interested in other tutorials like this!
I hope you’ll enjoy it!
Just do it… nothing stopping you.
Raycast documentation here.
If the attribute you want to use for “strength” is on your wrapped geometry then you just use it but if it is on the Target Geometry then you can pipe it through the Raycast node.
E.g. here the “strip” that the GN is applied to is wrapped to Suzanne and the offset is controlled by a vertex group on Suzanne (visualized in white).

Note the Normal is reversed because the “strip” Normals are pointing up (or more precisely, …
for the 2 sided geo thing… many ways to approach this, but you could just use the intersecting edges of any boolean operation between the scaled up and the extruded convex hull -
