Well, I was thinking of something much dumber.

I was thinking about just _carefully_ writing a single, self-contained C

Think of it is a step up in readability from straight assembly (which
was the stated reason for moving the code to the M3 in the first place.)

That can only give you your suspend function. You need a resume
function to undo everything before calling cpu_resume, and the resume
function needs access to the data that was in the suspend function.
