Blended Normals Bevel.
With this nodegroup you can blend objects in a collection.
An automatic bevel is created which blends your normals for a smooth transition between the meshes.
Manifold boolean is used for this setup so using closed solids is required.
If you want to use open geometry you can switch the bollean node to "float" or "exact".
