This definately sounds elegant, but it is quite a large amount of work.

This is the next best bet, I think. Here is a macro that does the
key work. You have to change the \message to do what you want:
\def\expandromannumerals#1%
{\expandafter\expandromannumeral\romannumeral #1\relax}
\def\expandromannumeral#1%
{\if #1\relax
\let\next\relax
\else
\message{#1}%
\let\next\expandromannumeral
\fi
\next }
\expandromannumerals{19}% call example
