Make GTK3 applications use the GTK2 dialog for font selection?

I prefer the user interface of the font-selection dialog of GTK2 to that of GTK3. How can I make GTK3 applications use the GTK2 dialog? EDIT: Unfortunately, Gnome doesn't let me take screenshots of the dialogs, so I am posting links. The font-selection dialog of GTK2 is on top of this page , whereas the font-selection dialog of GTK3 is on top of this page . I prefer the interface of the former dialog, so I would like all applications to use it instead of the latter dialog whenever I need to select a font.
