Hi, image/layer duplication is currently not possible in Batcher. I'll note this down as an enhancement in a future version. In the meantime, the workaround is to write a plug-in as Rich mentioned and add it as a custom action. You should then be able to manipulate the duplicate by selecting Layer Below (Background) or Layer Above (Foreground) (depending on the position the custom plug-in inserts the duplicate at) instead of Current Layer in subsequent actions.
In the future I plan to make a more generic (albeit more complex) approach where return values from one action could be used in another (e.g. add gimp-layer-new-from-visible and then gimp-image-insert-layer using the layer returned by the previous action).
