Mark,
It's probably not exactly what you're looking for, but there's a book
by Ivor Mairants, a British jazz guitarist, called "Arranging for the
Guitar" that you might want to try to track down. It talks about
some of what you're asking about. Jim Hall may also have some
stuff published, not sure. Rob Yellin has a bunch of books
that are completely chord melody, and you might find it useful to
look at them, not so much to play the tunes, as much as to see
and hear how he approaches this playing style. A lot of Rob's
material is somewhat too "thick" for me, but there are some real
gems scattered throughout his material. Howard Morgen also has
some arrangements you may want to track down.
Unless you take some theory and harmony classes in order to learn
for yourself, everything is going to sound "formulaic", because you're
being "told" how to do it, instead of learning it yourself. You may
also want to give pianist Bill Evans a listen, and try to adapt some
of his harmonic style into your playing. Good luck!
Cheers,
