I'm not sure what kind of changes themes can currently make. But
to make whatever changes are allowed you'd just write a theme. 
A simple theme can be an inline C string parsed with
gtk_rc_parse_string(). More complex ones might have to be installed.

The gtk-engines package (I think only in CVS now, no tarballs) has
several examples. And see docs on GtkRcStyle.

You can just bundle a custom theme with those apps. Anytime the user
is using two GTK apps on a system though, the reasoning applies.

Themes aren't just cosmetic. They are used to provide high-contrast or
large-font displays for disabled users, used to match the native
platform look-and-feel, that sort of thing; there are very good
reasons why application binaries should not be locking down
settings. So we place the burden on those apps that wish to do so.
