Imitate J Pol Econ titles

Question

I'm trying to imitate (not exactly replicate) the titles from the Journal of Political Economy (see e.g. the first page of this example), but have starting to stumble. My problem is that I can't define separate fonts for authors and affiliations. I have posted the result of my attempts thus far using the titling package at the bottom of the post.

I know that I could fix this using the authblk package, but I would prefer not to as it interferes with the hyperref package. I am in no way married to using titling. In fact, I think that it might actually be a better idea to redefine \maketitle altogether.

P.S. I am aware that it might be easier to just hardcode the title myself instead of using \maketitle but I would like to use this in a class eventually.

\documentclass{article}
\usepackage{array}
\usepackage{titling}
\makeatletter
\pretitle{\vspace{-60\p@}\begin{flushleft}\fontsize{22pt}{24pt}\selectfont\sffamily\bfseries}
\posttitle{\par\end{flushleft}\vskip 5em}
\preauthor{\flushleft\rule{\linewidth}{0.5pt}\begin{flushleft}\LARGE\sffamily\begin{tabular}[t]{@{}>{\raggedright}p{\textwidth}@{}}}
\renewcommand\and{%
  \end{tabular} \\[1em]%
  \begin{tabular}[t]{@{}>{\raggedright}p{\textwidth}@{}}}%
\postauthor{\end{tabular}\par\end{flushleft}}
\predate{\begin{flushleft}\normalsize}
\postdate{\par\end{flushleft}}
\makeatother
\title{On the Origins of the Philosopher's Stone}
\author{Albus Dumbledore \ Hogwarts School of Witchcraft and Wizardry, International Confederation of Wizards, and the Wizengamot \and Nicholas Flamel\Beauxbatons Academy of Magic}
\date{\today}
\begin{document}
  \maketitle
\end{document}

Answer 1

In the end, I redefined \@maketitle. I got help from Willie Wong to adjust Ruben's answer to another question and then I put some finishing touches on it.

One thing still bugs me though: perhaps there is something better than \empty to delimit the second argument of \FPA@formatauthor? Perhaps \empty is an outright bad choice? LaTeX is mystery to me.

\documentclass{article}
\makeatletter
\def\FPA@formatauthor#1\\#2\empty{{\LARGE\sffamily#1} \\ {\itshape#2}}% Format author affiliation pair
\def\FPA@author{}% Initialize \FPA@author
\def\split@and#1\and#2{% Populate \FPA@author recursively
  \g@addto@macro\FPA@author{\FPA@formatauthor#1\empty}
  \ifx#2\@nil\else
    \g@addto@macro\FPA@author{\par\vskip 3ex}
    \expandafter\split@and\expandafter#2\fi
}
\renewcommand{\@maketitle}{
  \newpage
  \let\footnote\thanks
  \expandafter\split@and\@author\and\@nil% Initialize recursion
  \flushleft
  {\LARGE\sffamily\bfseries\@title\par}
  \vskip 10ex\rule[2ex]{\linewidth}{0.5pt}
  {\FPA@author\par}
  \vskip 2ex
  {\@date\par}}
\makeatother
\title{On the Origins of the Philosopher's Stone}
\author{Albus Dumbledore\thanks{A footnote} \ Hogwarts School of Witchcraft and Wizardry, International Confederation of Wizards, and the Wizengamot \and Nicholas Flamel\ Beauxbatons Academy of Magic}
