Add a column to an existing multirow element

Question

I have the following code:

Main.tex:

\documentclass[11pt]{article}
\usepackage{techdoc}
\title{Lorem Ipsum is simply dummy text}
\subtitle{Lorem Ipsum is simply dummy text}
\department{R\&D}
\filepath{//path/to/file}

\begin{document}
\maketitle
\clearpage
\end{document}

techdoc.sty:

\ProvidesPackage{techdoc}

\RequirePackage[a4paper, hmargin=2.5cm, vmargin=1cm, includeheadfoot, headheight=3cm]{geometry}
\RequirePackage{fancyhdr}
\RequirePackage{array}
\RequirePackage{tabularx}

\RequirePackage{xspace}
\RequirePackage{lastpage}
\RequirePackage[bookmarks, bookmarksopen,pdfstartview={FitH},colorlinks,linkcolor={black},citecolor={black}, urlcolor={black}]{hyperref}

% fix some bug
\renewcommand{\nobreakspace}{\nobreak\ }

% make foot notes looks nice
\RequirePackage[hang]{footmisc}
\setlength{\footnotemargin}{7pt}

% Document information commands
\newcommand{\@confidentialitynotice}{Internal and Confidential Document}
\newcommand{\confidentialitynotice}[1]{\renewcommand{\@confidentialitynotice}{#1}}

% Tables
\definecolor{arrayrule}{rgb}{0.5, 0.5, 0.5}
\setlength{\arrayrulewidth}{0.5pt}
\arrayrulecolor{arrayrule}
\newenvironment{nicetable}{\begin{table}[h!t]\renewcommand{\arraystretch}{1.4}\addtolength{\tabcolsep}{3pt}\addtolength{\belowcaptionskip}{4pt}}{\end{table}}
\renewcommand{\arraystretch}{1.4}

% Title page
\setlength{\TPHorizModule}{1cm}
\setlength{\TPVertModule}{1cm}
\renewcommand{\maketitle}{%
    \newgeometry{headheight=0pt, headsep=0pt, hmargin=2.5cm, vmargin=2cm}
    \begin{titlepage}
    \begin{tabularx}{\columnwidth}{|>{\centering\arraybackslash}p{3cm}|>{\centering\arraybackslash}m{\columnwidth-6cm-4\tabcolsep-3\arrayrulewidth}|>{\centering\arraybackslash}p{3cm}|}
        \hline
        \multirow{2}{*}{\includegraphics[width=2.7cm, height=2.0cm]{icon_caution}} & {\bf \@confidentialitynotice } & {\includegraphics[width=2.7cm, height=2.7cm]{icon_goal}} \\[0.3cm] \cline{2-2}
        & \multirow{2}{*}{\bf  \@title}\\[.6cm] \cline{1-1}
        \@department & \\ \hline
    \end{tabularx}


    \vfill

    \begin{center}

    {\Huge \bf \@title}

    \rule{\columnwidth}{2pt}
    \vspace{0.1cm}

    {\LARGE \@subtitle}
    \end{center}

    \vspace{3cm}
    \vfill

    \end{titlepage}
    \setcounter{page}{2} % titlepage messes with my page counter!
    \restoregeometry
}

Which results in the following:

I would like to delete the last row, and instead create a new column on the right with only one case that would be the symmetric of the icon plus R&D.

I have tried the following:

\begin{tabularx}{\columnwidth}{|>{\centering\arraybackslash}p{3cm}|>{\centering\arraybackslash}m{\columnwidth-6cm-4\tabcolsep-3\arrayrulewidth}|>{\centering\arraybackslash}p{3cm}|}
    \hline
    \multirow{2}{*}{\includegraphics[width=2.7cm, height=2.0cm]{icon_caution}} & {\bf \@confidentialitynotice } & {\includegraphics[width=2.7cm, height=2.7cm]{icon_goal}} \\[0.3cm] \cline{2-2}
    & \multirow{2}{*}{\bf  \@title}\\[.6cm] \cline{1-1}
    \@department & \\ \hline
\end{tabularx}

Which results in this:

How can I improve it to make it look good?

Edit: The icons, as asked in the comments:

Answer 1

Something like this:

For above picture I make own MWE, since I'm lost in yours. I believe, that you will easily adopt it to your needs:

\documentclass{article}
    \usepackage[margin=25mm,showframe]{geometry}
    \usepackage{graphicx}
    \usepackage{multirow,tabularx}

\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}
    \begin{document}

{    \renewcommand{\arraystretch}{1.5}
\noindent%
\begin{tabularx}{\textwidth}{|P{3cm}|>{\centering\arraybackslash\bfseries}X|P{3cm}|}
    \hline
\multirow{3}*[2pt]{%
    \includegraphics[width=2.7cm,height=2cm]{example-image-a}}\smallskip~
    &   \rule[-3mm]{0pt}{9mm}
        Internal and Confidential Document\@confidentialitynotice 
        &   \multirow{2}*[2pt]{%
            \includegraphics[width=2.7cm,height=2cm]{example-image-b}}  
                        \\  \cline{2-2}
    &                                       
        &               \\
    &   Lorem Ipsum is simply dummy text%\@title     
        &               \\  \cline{1-1}
R\&D        &       &   \\  \hline
\end{tabularx}
}
    \end{document}

Answer 2

Here another solution, with a simpler code. I simplified a bit your package, removing packages which are alreay called by other packages, such as colortbl which is called by the table option of xcolor. Also, it is better to load hyperref after all other packages (there are some exceptions such as cleveref).

The main file: I loaded lmodern, instead of the default cm, in order to have italic boldface sans fonts.

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{techdoc}
\title{Lorem Ipsum is simply dummy text}
\subtitle{Lorem Ipsum is simply dummy text}
\department{R\,\&\,D}
\filepath{//path/to/file}

\begin{document}
\maketitle
\clearpage
