This is way too complex. Why don't you write a small
script/program/macro-processor that will pre-process a .ly file,
replacing

  \someWierdText

with

  \once \property Lyrics.LyricText \set #'X-extent = #(cons A B)
  "\\someWierdText"

where A B are the dimensions of the object, and might be computed
through a latex run.
