It looks like it would, but I've learned you have to try it to be sure. The problem seems to come when new() claims the option isn't legal for the package, or when you try to configure the object later, to modify the font. Or it may complain that -labelfont isn't an option of Frame.

Did you try it? I would but I'm lazy. :-) I know it can be made to work. If you are going to do it, you may as well allow options for all the fonts used( even the list fonts).
