Hello,

Do not ask me how since I don't speak LaTeX, but I bet that you can
get transparent fonts with some macro package. This tiny ConTeXt
example uses xdvipdfmx and generates transparent text without any
problem. I'm sure that there's an equivalent way to do the same in
XeLaTeX.

\setupcolors[state=start]
\definecolor[c1][r=1,t=.5,a=1]
\definecolor[c2][g=1,t=.5,a=1]
\definecolor[c3][b=1,t=.5,a=1]

\def\test#1#2{\hbox to 1ex{\color[#1]{#2}\hss}}
\starttext
\hbox{\test{c1}{this}\test{c2}{is}\test{c3}{transparent}}
\stoptext
