Have you looked at
<http://thread.gmane.org/gmane.comp.gnu.lilypond.general/56071/focus=56151>
I recognize that it takes a different tack than you want, because it only
goes note for note instead of chord for chord. But it shows the way to get
the spacing you want and to avoid the clashing note columns.
\once \override Glissando #'minimum-length = #5
\once \override Glissando #'springs-and-rods =
#ly:spanner::set-spacing-rods
is the way to get the spacing. To avoid the clashing note columns, you
could do
\override NoteColumn #'ignore-collision = ##t
before your function, and
\revert NoteColumn #'ignore-collision
after the function.
It would be pretty simple for you to adjust the inner workings of
chord-glissando.ly to make it work by rotating the chord, rather than by
carving out individual notes.
HTH,
Carl
