I didn't address the fact that `clone-buffer' won't work with a
file-visiting buffer, as you noted. Also, `with-temp-buffer' is probably
an even better fit than `with-current-buffer', if you don't need that
buffer to stick around when you're done.
Here's another example approach, hopefully more useful:
(let ((buffer (current-buffer)))
(with-temp-buffer
(insert-buffer-substring buffer)
(insert "\nStuff happening!\n")
(write-region (point-min) (point-max) "~/destination.txt")))
