This is similar to how MinionPro deals with open vs closed mathematical g's.
\documentclass{article}
\mathcode`l="8000
\begingroup
\makeatletter
\lccode`\~=`\l
\DeclareMathSymbol{\lsb@l}{\mathalpha}{letters}{`l}
\lowercase{\gdef~{\ifnum\the\mathgroup=\m@ne \ell \else \lsb@l \fi}}%
\endgroup
\begin{document}
\( l = 2 \) \( \lim = 2 \)
\end{document}
