I have spent many hours attempting to reproduce fisheye-hemi using lensfun inside darktable. I couldn't get anywhere close to it. I think that is because fisheye-hemi doesn't really correct a lens fault, it is more like applying a creative distortion. Lensfun is great for corrections, but the fisheye-hemi effect seems to be a long way outside the parameters that lensfun allows.
