Hi Susan:

This seems to be a perfect case for XeTeX interchartoks!

This works, but you'll want to change the Scale for the \tgb font  
I've used here (I made an exaggerated example so it could be seen to  
work).



%%%%%%%%%%%%%%%%%%%%%
\documentclass[11pt]{article}

\XeTeXinterchartokenstate = 1

\usepackage{fontspec, realscripts}
\usepackage{polyglossia}
\setdefaultlanguage[variant=us]{english}
\defaultfontfeatures{Ligatures=TeX}
\setmainfont[Numbers={OldStyle,Proportional}, Contextuals=NoAlternate] 
{Garamond Premier Pro}

\newfontfamily\tgb[Scale=2]{TeX Gyre Bonum}

\XeTeXinterchartoks 0 4 = {\tgb}
\XeTeXinterchartoks 4 0 = {\normalfont}
\XeTeXcharclass `\– 4
\XeTeXcharclass `\— 4
\XeTeXinterchartoks 255 0 = {\normalfont}
\XeTeXinterchartoks 0 255 = {\normalfont}
\XeTeXinterchartoks 255 4 = {\tgb}
\XeTeXinterchartoks 4 255 = {\normalfont}


\begin{document}
Try this — I mean does it really work from 2–3 times?
\end{document}
%%%%%%%%%%%%%%%%%%%%%



HTH.
