Not sure I quite get that! If Pacers were a cheaper operational option, then transfering them to lines more at risk would help, so perhaps Cornwall wasn't so much at risk - have I misunderstood you?
What I'd like to know is, what are the actual services they did help to save.
AFAIK Pacers saving lines is just a rumour. Considering 101s managed to stay in operation until 2001 I don't see how building new trains in 1985 to replace first gen DMUs was to save lines.
Pacers being removed from Cornwall was nothing to do with Cornish lines being safe from closure - the curvy track was causing the wheels on Pacers to wear out too quickly for BR's liking.
What happened was something like this (numbers aren't accurate):
142s in operation in Cornwall: 15 (30 carriages)
Number of 150s that were sent down to Cornwall in exchange for the 15x142s: 8 (16 carriages)
Net gain in carriages for North through 142 cascade: 14 carriages.
142s in operation in Cornwall: 15 (30 carriages)
Number of 150s that replaced 142s in Cornwall: 8 (16 carriages)
Number of 2 car 142s in Cornwall that were replaced by single carriage units (Bubble cars, then 153s): 7
Net loss in carriages for Cornwall through 142 cascade: 9 carriages.
I'd tried to explain that previously as well as I can without giving any numbers so had to invent some to try and illustrate it more clearly.
Based on what Oswyntail said in an above post about the North getting a net gain in Pacers because passenger numbers were picking up I would imagine Cornish passenger numbers continued to drop in the 1980s so they suffered from a net loss in carriages as a consequence. Replacing 142s with single carriage trains on some Cornish routes may well have saved lines there as there would have been less empty seats.
