Defining commands to select different package fonts

I would like to have two different font styles in my document that are, unfortunately called by the same command.

I would like to have \mathscr{} as called by the package eucal with the mathscr option. Additionally, it would be very helpful to have the \mathscr{} as called by the package mathrsfs.

Is there a way to define commands at the beginning of my document so I only need to use one of these packages while have the font effect from the other package?

-

\documentclass{article}
\usepackage{mathrsfs}
\DeclareSymbolFontAlphabet{\mathrsfs}{rsfs}
\usepackage[mathscr]{eucal}

\begin{document}

$\mathcal{ABC}\mathscr{ABC}\mathrsfs{ABC}$

\end{document}

That works great, thanks a lot. – gj herrmann Feb 20 '12 at 5:24
