Well as long as \thepage give a simple number you can use refcount:

\documentclass{article}
\usepackage{refcount}
\usepackage{lastpage}
\newcounter{mypage}

\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\cfoot{\addtocounter{mypage}{-1}\themypage}

\begin{document}
\setcounterpageref{mypage}{LastPage}
abc\newpage cd\newpage ef\newpage gh
\end{document}
