I think using buffer-swap-text, you should be able to fairly easily make
it so that cpio-mode is a proper major mode (e.g. doesn't change
current-buffer) and yet moves the current buffer's contents to some
auxiliary buffer and puts the dired-style interface in the current buffer.
(and setup a change-major-mode-hook to reverse this if the user decides
to change the major mode to something else like fundamental-mode).
