Would be far better to edit the theme, rather than meddle with the font. Basically you need to change the viewport used by the menus to start with an X co-ordinate a bit larger than 0 (5 maybe...depending how much space you want to leave at the left side).
Right now I've forgotten everything I used to know about themes, and am not in a position to test it right now, but on first glance I _think_ (IIRC) it's the line
%Vi(-,0,19,160,221,1)%Vf(000000)%Vb(FFFFFF)
in the sbs file you need to change, maybe to
%Vi(-,4,19,156,221,1)%Vf(000000)%Vb(FFFFFF).
There might be more things that need to be amended than that, without trying it out I'm not sure, as everything about writing themes has disappeared from my brain, but it's definitely the theme you'd need to amend, not the font.
