Chapter number in left right margin

Question

I would like to move the chapter number in the right margin (a bit like in the classicthesistheme) but all I tried just results in errors, it would be nice if some could have a look. My MWE is using scrreprt and I can't move to the memoir class.

\documentclass[
fontsize=12pt,

parskip=half,      
ngerman,

        \raisebox{\depthof{\usebox{\feline@chapter}}}{\usebox{\feline@chapter}}%
    }


            \newcommand\feline@chm[1][4cm]{%
                \sbox\feline@chapter{\feline@chapter@marker[#1]}%
                \makebox[0pt][l]{% aka \rlap
                    \makebox[1cm][r]{\usebox\feline@chapter}%
                }
            }

Here is a another suggestion

\documentclass[
fontsize=12pt,
twoside,
a4paper,
parskip=half,
ngerman,
headings=big,
open=right
]
{scrreprt}

\usepackage[english,german]{babel}
\usepackage[utf8]{inputenc}
\usepackage{color}
\usepackage{blindtext}
%\usepackage{showframe}

\DeclareMathAlphabet\EuRoman{U}{eur}{m}{n}
\SetMathAlphabet\EuRoman{bold}{U}{eur}{b}{n}
\newcommand{\eurom}{\EuRoman}

% Define own Chapter style
% Pretty chapter pages
%------------------------------------------
\definecolor{nicered}{rgb}{.647,.129,.149}
\usepackage{pdfpages}
\usepackage{etoolbox}

\makeatletter
\newsavebox{\feline@chapter}
\newcommand\feline@chapter@marker[1][4cm]{%
  \sbox\feline@chapter{%
    \resizebox{!}{#1}{\setlength{\fboxsep}{0pt}%
        \colorbox{white}{\color{black}$\eurom\thechapter$}}}%
  \raisebox{\depth}{\usebox{\feline@chapter}}%
}
\renewcommand*{\chapterformat}{%
  \sbox\feline@chapter{\feline@chapter@marker[1.61cm]}%
  \makebox[0pt][l]{%
    \makebox[\dimexpr\textwidth+\marginparsep+\wd\feline@chapter\relax][r]{%
      \usebox\feline@chapter}}%
}
\makeatother

\preto\chapterheadendvskip{%
  \vspace*{-\parskip}%
  {\noindent\setlength\parfillskip{0pt plus 1fil}\rule{\textwidth}{.4pt}\par}%
}

\begin{document}
\tableofcontents
\chapter{Lorem ipsum dolor sit amet, consectetuer adipiscing elit}
\blindtext[2]
\end{document}

Note that I would use open=right if the chapter number should be in the right margin.

Result:

Update as answer of a comment below:

If you want to use \MakeUppercase for the chapter titles you can redefine \chapterlinesformat. Note that the following example needs at least KOMA-Script version 3.19:

\documentclass[
fontsize=12pt,
twoside,
parskip=half,
ngerman,
headings=big,
open=right
]
{scrreprt}[2015/10/03]

\usepackage{babel}
\usepackage[utf8]{inputenc}
\usepackage{xcolor}
\usepackage{graphicx}
\usepackage{etoolbox}

\usepackage{blindtext}

\DeclareMathAlphabet\EuRoman{U}{eur}{m}{n}
\SetMathAlphabet\EuRoman{bold}{U}{eur}{b}{n}
\newcommand{\eurom}{\EuRoman}

\makeatletter
\newsavebox{\feline@chapter}
\newcommand\feline@chapter@marker[1][4cm]{%
  \sbox\feline@chapter{%
    \resizebox{!}{#1}{\setlength{\fboxsep}{0pt}%
        \colorbox{white}{\color{black}$\eurom\thechapter$}}}%
  \raisebox{\depth}{\usebox{\feline@chapter}}%
}
\renewcommand*{\chapterformat}{%
  \sbox\feline@chapter{\feline@chapter@marker[1.61cm]}%
  \makebox[0pt][l]{%
    \makebox[\dimexpr\textwidth+\marginparsep+\wd\feline@chapter\relax][r]{%
      \usebox\feline@chapter}}%
}
\renewcommand\chapterlinesformat[3]{%
  \ifstr{#1}{chapter}
  {\@hangfrom{#2}{\MakeUppercase{#3}}}
  {\@hangfrom{#2}{#3}}%
}
\makeatother

\preto\chapterheadendvskip{%
  \vspace*{-\parskip}%
  {\noindent\setlength\parfillskip{0pt plus 1fil}\rule{\textwidth}{.4pt}\par}%
}

\begin{document}
\tableofcontents
\chapter{Lorem ipsum dolor sit amet, consectetuer adipiscing elit}
\blindtext[2]
\end{document}

Trying, to change the chapter headline with \addtokomafont{chapter}{\normalsize\MakeUppercase} (\MakeUppercase is from \usepackage{textcase}) leads to the error message ! Missing number, treated as zero.,! Color stack action is missing. and ! Missing number, treated as zero. Do you have any clue how to prevent this from happening? — jlk, Sep 09 '15 at 14:23

I am still trying to understand the commands, so I have no idea on how to obtain the effect I need: to have the chapter number at the right, but two lines above the chapter name. Can you help here? — Leandro, Feb 26 '17 at 02:22
@lfd You could use \raisbox to shift the chapter number: \renewcommand\chapterlinesformat[3]{ \ifstr{#1}{chapter} {\@hangfrom{\raisebox{3\baselineskip}{#2}}{\MakeUppercase{#3}}}{\@hangfrom{#2}{#3}}} — esdd, Feb 27 '17 at 23:29

Fine, but it is not recommended to use titlesec if you use the koma-script classes. — Bernard, Sep 01 '15 at 14:48
