Sorry this is not a simple solution. Making numbers active on the
document level will lead to a lot of problems and whoever does it
will have to learn a lot of intricacies of TeX to get around them.
Parameters (#1) are only the top of the iceberg. The next is eg
this:

\documentclass{article}
\usepackage{listings}
\begin{document}

\chardef\one=1
\catcode`\1=\active
\def1{\string1}

\begin{lstlisting}[linerange=1-2]
 a
 b
 c
 d
\end{lstlisting}
\end{document}

And please don't repeat that you "was not in any
way trying to suggest that this is a general or universal
solution.". You _did_ sent the first example without any code which
restricted the effect of the catcodes changes and without any
warnings about side-effects. This was the posting I commented as
this is not my idea of an helpful answer.
