¿Puedo cambiar la posición de las marcas de recorte de geometría que muestran la misma área de recorte?

Question

Me pregunto si puedo dejar más espacio entre las geometrymarcas de recorte y el texto mismo. No quiero cambiar el área recortada.

MWE demuestra un comportamiento obvio de geometrylas marcas de corte.

\documentclass{book}
\usepackage{lipsum}

\usepackage[ paperheight  =297mm,paperwidth   =210mm, 
             layoutheight =197mm,layoutwidth  =130mm,
             layoutvoffset= 50mm,layouthoffset= 40mm,
             margin=0pt, includeheadfoot,
             showcrop=true]{geometry}

\begin{document}
\chapter{In the Beginning}
\lipsum
\end{document}

Macro \cropmarkgap ajustable de 0 a 20 (mm).

\documentclass{book}
\usepackage{lipsum}

\usepackage[ paperheight  =297mm,paperwidth   =210mm, 
             layoutheight =197mm,layoutwidth  =130mm,
             layoutvoffset= 50mm,layouthoffset= 40mm,
             margin=0pt, includeheadfoot,
             showcrop=true]{geometry}

\def\cropmarkgap{10}% mm

\makeatletter
\def\Gm@cropmark(#1,#2,#3,#4){% #1 = x direction, #2 = y direction, #3 & #4 no longet used
  \begin{picture}(0,0)
    \setlength\unitlength{1truemm}%
    \linethickness{0.25pt}%
    \put(\the\numexpr #1*\cropmarkgap\relax,0){\line(#1,0){\the\numexpr 20-\cropmarkgap}}%
    \put(0,\the\numexpr #2*\cropmarkgap\relax){\line(0,#2){\the\numexpr 20-\cropmarkgap}}%
  \end{picture}}%
\makeatother
