That sounds simple, but wouldn't the ebook you "pulled off" the Kindle still be in Amazon's format with DRM? I don't think this solves the original problem.
The first problem was to get the original file from somewhere in a usable format, then strip DRM in a later stage. Seems like step 1 was already made significantly harder now.
I tried to do this recently but discovered that the DRM algorithm changed and I couldn't use the standard de-DRM tools.
