I would say this is a prime use case for the edition-engraver that 
allows you to inject a \break based on measure number (regardless of 
time changes along the way). Presumably you can make life even simpler 
using the openLilyLib package "page-layout" (depending on "breaks" and 
"edition-engraver").

With this you can register "break sets" with line breaks, page breaks 
and page turns and assign them to a label (e.g. score, violinI, 
violinII, va, vc). Then in the individual part file you'd say 
\applyConditionalBreaks violinII.

The usage example 
https://github.com/openlilylib/page-layout/blob/master/usage-examples/conditional-breaks.ly 
should give you a quick idea, although it is done for 
manuscript/original-edition.
