Sorry, I didn't see this because of the [misleading] subject :-(  Next time,
either reply to the [single] message directly, or at least modify the subject
line to match the current thread.

You're command is incorrect - there is a big difference between "_"
and "-" when it comes to bitbake parsing.  Try this:
   SRC_URI_append_image_name2 = "file://XYZ.patch"
                       ^
Notice this uses underscore (_) not hyphen (-)

Of course I could just copy one to another, but then there's the problem of updating files later on. Therefore, unless there is another option that I haven't considered, I might look at refactoring everything into a .inc file and have two different  recipe names of which I can then include seperately in the respective images.
