I think the answer is you are going to have to continue to do this manually unless you write a plugin to do it. All the automatic methods I can think of will put the cover into the book in an SVG wrapper. And the reason they do that is they are all calling the same calibre code to do it. If you are willing to run calibre from source code, it is possible to make changes that would produce what you want.
But, I'm curious about why you don't want the SVG wrapper for the cover image. As far as I can tell, that is the best way to display the image. When people ask the question about how to add cover in the Workshop forum, code similar to what calibre uses is suggested. The suggestion isn't coming just from calibre users, but professional ebook creators as well.
