You can use Calibre's Modify Epub plugin with Insert or replace cover checked and then keep the original file (shows as ORIGINAL_EPUB format) until you are happy and then bulk delete the ORIGINAL_EPUB files. If the book is messed up, I copy the original_epub to a temp directory and rename it, delete the epub and original_epub in Calibre (not removing the book but removing files of a specific format) which leaves the metadata and cover image and then drop the renamed file on the details view (on top of the cover image works for me) to place it back in the library.
