Should we discuss this here, or make a new thread?
If size changes count as damage, which the 'if, then' statement requires to fire (...if the statue resulting from this spell is broken or damaged, then...'), then it works. I don't see that size changes count as damage, so the flesh to stone spell's clause doesn't look like it's a path to a 'free' permanent (effectively the same as instantaneous; as it's not dispellable) shrink item effect.
