I've had minor success by attempting to force the boundary on both meshes to be a Transfinite Line with shared parameters, however, when I introduce internal hole geometry within the inner mesh domain I can not get the mesh boundary to be conformal.

The default behavior of Gmsh is to generate such conformal meshes, if the boundary curve is unique. How did you generate your geometry?
