Well, I played some more and piping to cpio did the trick. I couldn't do
it in one go as pass mode doesn't support the interactively rename switch,
but a temporary copy out followed by an interactive copy in worked.

I then tried pax -rwi which was even more efficient as it let me rename
while find was creating the list.
