Would any of you have a suggestion on how best to achieve the deformation of the nodes to match the manifold?

I suspect that this depends a lot on how exactly your manifold is given. You need some projection onto the manifold. If you used IGES CAD files, such projections are built-in with OpenCASCADE. For constructive solid geometry cases, it may be possible to build the project from known normal vectors. I expect that the situation becomes complicated in the "creases" where two boundary patches come together.
