As I think some more about it, this may be more possible than I thought. 
 It looks like everything in lilypond-book-preamble.ly is a scheme 
expression (except for the `\version` statement) as is 
`#(set-global-staff-size 11)`.  That covers most of what I need to 
change (so far at least) on a project by project basis.  The only other 
thing is a `\paper` block (it's setting line-width and indent).  Is 
there a way to set a top level `\paper` block entirely within Scheme?
