sorry about the confusion... that question technically wasn't directed towards you.
never mind that though. i figured it out with some quick tests and the answer is yes.
what fonts would you like to use for the different things?
edit: all i will be able to do though, is make it so the menus are one font, wps another, and another for plugins and such(text editor and viewer included).
edit II: this is my plan for you... i will modify that theme to use its regular font for wps and menus. and which ever font you want for the plugins.
edit III: which font did you want for the text viewer?
