I understand where you are going with this, but seriously, it would be a right pain in the *** to delete all of your data (and be SURE you had deleted EVERYTHING) and then make an image primarily for others to use, before restoring all of your data. You would also have to be sure you did not include any paid apps in the image.

This makes me think that perhaps there is an opportunity for the maker of backupmenu to consider if this is possible for a future version of his app - make a data-free image for the purposes of problem solving / troubleshooting?
