I think it might be possible to do something even less complicated.
The basic idea is to first borrow this from the manual:

  zle -C all-matches complete-word _generic
  bindkey '^Xa' all-matches
  zstyle ':completion:all-matches::::' completer \
                 _all_matches _complete
  zstyle ':completion:all-matches:*' insert true

And then:

  do-complete() { zle -U $'\Cxa\n' }
  zle -N do-complete
  run-complete () {
    vared -i do-complete argv
  }
  complete() {
    local -i n=$argc
    zpty complete-tty run-complete "$@"
    zpty -r complete-tty
    zpty -d complete-tty
  }

There is likely some additional quoting needed on $@ to assure the
right arguments are passed to run-complete, and some more could be
done to separate the context from the results.
