No, because the help text is generated at autoconf-time (using m4
diversions).  Check where your help text ends up in the generated
configure, and you'll see why.

[I did do exactly what you want when I was using autoconf 2.13, by
(ab)using m4 diversions myself, but this relied on the internals of
autoconf, which was not maintainable, so I stopped doing it...]
