I compile Lilypond instead of using GUB, and I apply the attached patch 
to make shape-notes wider.  They are a bit narrower than 2.7, but 
considerably wider than 2.8.  It would be nice if the width of the 
shaped heads could be tuned within a .ly file, but right now I don't 
have any disposable cash to make that happen.

Both 4-shape and 8-shape scales have noteheads exactly as wide as the 
round noteheads in all published sources I can find.  I can send scans 
if you like.  An online example can be found here:
