You can even set self-alignment-X itself to a callback, like in the 
attached (slightly overcomplicated) library file I use for lyrics 
alignment. In this example, all lyric syllables up to a width of 3 
(staff-spaces, I guess) get the default self-alignment-X of 0, all lyric 
syllables wider than 11 get -.8, and values between are interpolated.
