Why not write your own little widget function? Like so:

  expand-last-word() {
    local word="${(M)LBUFFER%%[^ 	\;\|\{\}]##}" exp

    if (( $+commands[$word] )); then
      exp="$commands[$word]"
    elif (( $+aliases[$word] )); then
      exp="$aliases[$word]"
    fi

    [[ -n "$exp" ]] && LBUFFER="${LBUFFER%$word}$exp"
  }
  zle -N expand-last-word
  bindkey ... expand-last-word

Plus obvious improvements: The pattern in the first line should match
only thos characters that should be considered part of the word. If
the cursor is after a space (or other non-word characters) it could
search back for the word to expand. It could append a space to the
string inserted. Etc.
