원하신 대로 된 건지는 모르겠지만요,

일단 다음과 같이 해봤슴다.

\usepackage{everypage}

%%% ... 

\AddThispageHook{%

\tikz[remember picture,overlay] \node at (current page.center) 

 {%

    \begin{tikzpicture}

      \node[minimum width=\textwidth, minimum height=\textheight, anchor=north west] (a) {};

      \draw [thick, blue] (a.north west) -- (a.south east);

      \draw [thick, blue] (a.north east) -- (a.south west);

      \draw [line width=3pt, red] (a.north west) rectangle (a.south east);

    \end{tikzpicture}

 };

}

다음 그림은 

 \usepackage{fapapersize}

 \usefapapersize{150mm,101mm,10mm,*,12mm,*}
