Indeed you can "\input random.tex" at the beginning of your document and
replace \extractletters in my original code with this new definition:

    \def\extractletters#1{%
      \def\rest{}%
      \ifnum\letters>1
        \setrannum{\random}{1}{\letters}%
        \advance\letters-1 \scratch=1
        \getletter#1\endofword%
      \else
        #1%
      \fi
      }

Best,
Paul
