Unfortunately, that's not possible. GUILE's safe mode revolves around
namespace trickery to hide 'unsafe' commands. Unfortunately, LilyPond
scoping also uses namespace trickery, and I don't see how I can
mix both things flawlessly.

For making pngs, it should   suffice to do

    lilypond --safe --png

no need to copy preambles from lilypond-book
