This seems a promising idea, and I was cross with myself that I had not
spotted \abs-fontsize for myself.

But now that I have tried it, I am getting a bizarre result: the titles
in the score are as specified in my version of bookTitleMarkup; but
although the parts have the correct font-sizes, both vertical spacing of
the lines and horizontal spacing of individual letters is abnormal, and
is in proportion to the staff-size set.  Try as I might, I can't work
out why this is happening.

The basic structure I have, missing out everything that appears to be
irrelevant, is this:

\version "2.18.0" 

%'include' file containing definition of myBookTitleMarkup

titleStr = "Title"
subtitleStr = "Subtitle" 

\paper {
  bookTitleMarkup = \myBookTitleMarkup
}

#(set-global-staff-size 16)

\book {
  \bookOutputName "score"
  \header {
    title    = \titleStr
    subtitle = \subtitleStr
  } 
  \score  { }
  \layout { }
}

#(set-global-staff-size 20)

\book {
  \bookOutputName "part1"
  \header {
    title    = \titleStr
    subtitle = \subtitleStr
  } 
  \score  { }
  \layout { }
}
