\,(downcase \1)

can be used in Emacs 22 in the replacement text.  Sure, it is more
verbose, but also quite more flexible.  The Emacs manual has:

    For example, to add consecutively numbered strings like `ABC00042' to
    columns 73 to 80 (unless they are already occupied), you can use

         M-x replace-regexp <RET> ^.\{0,72\}$ <RET>
         \,(format "%-72sABC%05d" \& \#) <RET>
