Turned out to be pretty simple (although hacky, as always with LaTeX ;-)

Together with the previous change, the diffpreamble.tex could look like
this:

8<--------------------
%DIF FONTSTRIKE PREAMBLE
\RequirePackage[normalem]{ulem}
\providecommand{\DIFaddtex}[1]{{\color{blue}\sf #1}}
\providecommand{\DIFdeltex}[1]{{\color{red}\footnotesize \sout{#1}}}
%DIF END FONTSTRIKE PREAMBLE
%DIF COLOR PREAMBLE
\RequirePackage{color}
\providecommand{\DIFaddbegin}{}
\providecommand{\DIFaddend}{}
\providecommand{\DIFdelbegin}{\hypersetup{linkcolor=red,urlcolor=red}}
\providecommand{\DIFdelend}{\hypersetup{linkcolor=green,urlcolor=green}}
%DIF END COLOR PREAMBLE
% Standard \DIFadd and \DIFdel are redefined as \DIFaddtex and \DIFdeltex
% when hyperref package is included.
%DIF HYPERREF PREAMBLE
\providecommand{\DIFadd}[1]{\texorpdfstring{\DIFaddtex{#1}}{#1}}
\providecommand{\DIFdel}[1]{\texorpdfstring{\DIFdeltex{#1}}{}}
%DIF END HYPERREF PACKAGE

%DIF FLOATSAFE PREAMBLE: SEEMS UNUSED BUT JUST IN CASE
\providecommand{\DIFaddFL}[1]{\DIFadd{#1}}
\providecommand{\DIFdelFL}[1]{\DIFdel{#1}}
\providecommand{\DIFaddbeginFL}{}
\providecommand{\DIFaddendFL}{}
\providecommand{\DIFdelbeginFL}{}
\providecommand{\DIFdelendFL}{}
%DIF END FLOATSAFE PREAMBLE
