I have a very simple solution that will work very well. Use the Modify ePub plugin. There is an option to insert or replace the cover. IT does as little as possible to change any of the code. See the screen grab to see what the option is you'd need to select in order to fix the cover. You can do this for multiple ePub in one go. It works very well. It will keep the correct aspect ratio. This is the best solution for updating the cover for ePub.
