Well, going to the start and using down-case-word (ESC l in Emacs mode)
until you get to the end is the obvious way.

But it's not hard (after you've worked out the offsets, anyway) to write
a widget that transforms the region---I hadn't realised there wasn't
one:

  down-case-region() {
    emulate -L zsh
    integer p1 p2

    if (( CURSOR < MARK )); then
      (( p1=CURSOR+1, p2=MARK ))
    else
      (( p1=MARK+1, p2=CURSOR ))
    fi
    BUFFER[p1,p2]=${(L)BUFFER[p1,p2]}
  }
  zle -N down-case-region

Unfortunately ${(L)...} and parameter indexing don't handle multibyte
characters yet, so down-case-word, which is implemented internally,
should be safer.  You could use some kind of hybrid.

I was hoping for a history modifier eg
^^^ or !!:s///
but they don't seem to support wildcards?

You should have said that earlier...

!!:l

will turn the whole previous line into lower case.  Do you only want a
certain range of words?  You can do tricks like:

% ECHO THIS NEXT WORD IS UPPERCASE
zsh: command not found: ECHO
% !!:-:l !!:$
% echo this next word is UPPERCASE

The word selector - is short for 1- which is short for 1 to the word
before the last.  The word selector $ is the last word.  So you get all
but the last word in lower case, then the next word as it was.

Or just lowercase the command 
!!:0:l !*
