You have to write the "read back" routines yourself too, so it depends
on how you write those.  Probably reading them as a lisp file is
easiest, so dump

widths.scm containing

  '(("foo" .  2.0)
    ("bar" . 3.0)
    ("baz" . 3.5))

and eval that. Then write a function to transform it to
the internal equivalent of

\lyrics {
  { \override LyricText #'width = #'(0 . 2.0)
    foo
  }
  { \override LyricText #'width = #'(0 . 3.0)
    bar
  }
  { \override LyricText #'width = #'(0 . 3.5)
    baz
  }
}
