This approach has a problem: Once you change a note (say, fix a typo) and need 
to re-run lilypond, you will have to redo all tweaks again.

You may want to take a look at the experimental gnome back-end, which has 
existed for quite some time now (2.4 or 2.6, IIRC), but which for some reason 
never became popular. It offers a better solution to your problem: The score 
is displayed on the screen, and you can adjust spacing by drag-and drop, and 
save all modifications in a separate file (containing tweaks). This way you 
can still make musical corrections in the .ly file without having to redo all 
spacing tweaks (except, of course, if your musical corrections themselves 
affect spacing sufficiently to invalidate your tweaks).
