You could subclass Tk::CollapsableFrame, with Tk::Derived, and probably add a font option. Google for Tk::Derived for examples, it's pretty easy once you get used to it.

An even easier way would be to just copy CollapsableFrame.pm to MyCollapsableFrame.pm and edit it to add the font option. You will need to do what is shown in perldoc Tk::Derived: 

#-------------------------------------------------------------------
#take care of args which don't belong to the SUPER, see Tk::Derived
my $font = delete $args->{-font};
if( defined $font ) { $self->{'font'} = $font }
#-----------------------------------------------------------------
