I'm using \ssearrow to denote a deformation retraction in algebraic topology. I want to use the same arrow, but with two heads for a strong deformation retraction. It doesn't exist in MnSymbol.

Is there a way to add another head to \ssearrow?

\usepackage{amssymb,graphicx}
\def\SSEarrow{\ensuremath{\rotatebox[origin=c]{-60}{$\twoheadrightarrow$}}}
\begin{document}

\Huge\SSEarrow
\end{document}
