The mesh for something like this is always huge. Is there a way to treat the thin layers as 2D shells, while keeping the thicker ones 3D? The model is being exported as a STEP file and brought into Gmsh.

Just include the surfaces in your model; Gmsh generates conformal meshes so this internal surface can then be treated as a thin layer in your solver. If you need duplicated nodes on the surface (which Gmsh normally does not generate), you can run Plugin(Crack) on the resulting mesh.
