I've dug up some examples of [r'] > [z] and of [Z] > [z]. I found
them at http://www.linguistlist.org/issues/6/6-1627.html . The
description goes,

'Similarly, it is not hard to get from a palatal /r'/ to /z/.
Some Polish dialects change */z^/ to /z/ and later most Polish
dialects change */r'/ to /z^/. If the changes had occurred in the
reverse order, then we would had have a change of */r'/ to /z/ over
a large area of Poland. In reality, we do find this ordering in
some score of villages located around the periphery of the /z^/ to
/z/ change.'
