Why would you need to change buffer-file-coding-system in this
situation?  If you wanted to get Emacs to display the buffer
differently, then changing buffer-file-coding-system won't cut it: it
only changes how Emacs will save the buffer, but does nothing to
buffer's text.

To have the file decoded differently, kill the buffer and visit it
again, this time using "C-x RET c CODING-SYSTEM RET" immediately
before find-file-read-only.

The fact that Emacs sets the buffer's modified flag when you change
the buffer's coding system is a feature: it reflects the fact that the
file on disk would have been changed if you save it.
