PS: JFTR

[rocketmouse at archlinux ~]$ grep font .config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml 
    <property name="title_font" type="string" value="Sans Bold 11"/>

You could grep all config files for the fonts and test if switching
between configs automatically is applied. IOW make e.g. xfwm4.xml a link
switching between xfwm4.xml.1 and xfwm4.xml.2.
