Great idea!  Thanks for your suggestions.

By the way, I fixed the outlines of G and u, but there's room for
improvement.  I used the 'Stroke' menu to increase the weight.  It would
be better to redraw the whole thing in FontForge.  However, it's not in
my short-term to-do list; there are so many things to implement.

Will do.
