Reading this, I recalled a Ross Moore reply to the TeX on Mac OS X
mailing list, which you can see here (yes, 2004):

Crudely adapting his code, one can construct something like this:
\documentclass[11pt]{article}
\newcommand{\fracoffrac}[2]{\mathchoice
{\raise.25ex\hbox{$#1$}\hbox{\large$\mkern-2mu/\mkern-2mu$}\lower.
25ex\hbox{$#2$}}%
{\raise.25ex\hbox{\small$#1$}\hbox{$\large\mkern-1mu/\mkern-2mu$}
\lower.25ex\hbox{\small$#2$}}%
{\raise.15ex\hbox{\small$\scriptstyle#1$}/\lower.15ex\hbox{\small$
\scriptstyle#2$}}%
{\raise.1ex\hbox{\small$\scriptscriptstyle#1$}/\lower.1ex\hbox{\small
$\scriptscriptstyle#2$}}%
}
\begin{document}
\[
\fracoffrac{\frac{1}{2}}{\frac{3}{4}}
\]
In text mode: $\fracoffrac{\frac{1}{2}}{\frac{3}{4}}$, and some more
text.
\end{document}
Best,
Axel
