Probably.  What theme is yours based on?

The "highlight" element from the "classic" theme might do what
you want -- it just calls Tk_DrawFocusHighlight() with values 
derived from the -highlightthickness and -highlightcolor 
element options.

You can import it into your theme with:

    style element create highlight from classic

and use it like:

    style layout TButton { 
    	TButton.highlight -children { ... } 
    }
    style default TButton -highlightthickness 1 
    style map TButton -highlightcolor \
    	[list focus $accentColor {} $frameColor]

You could also change border colors (this is how
the 'clam' theme draws the focus ring for entry widgets,
for instance).  How to do this depends on which border
element you're using.
