What about the existing pitch-repeating functionality in LilyPond?

%%%%
\version "2.22.0"

foo = { 4 4 }
{ b'2 \foo g' \foo }
%%%%

A duration without pitch is encoded as a NoteEvent with the pitch 
property.  expand-repeat-notes! is the internal procedure that carries 
over the most recent pitch.  So long as you insert these events early 
enough, LilyPond should do the heavy lifting for you.
