As I understand it, Fosc is always the clock that goes to the processor, and
Fosc/4 is that same clock divided by 4.  So I conclude that CLKO is always
going to reflect the clock that is selected to go to the processor.  I
should say, "ultimately selected", since figure 2-1 shows there are quite a
few switches between the oscillators and the processor (and other
destinations).

It appears it will give you what you want.  I haven't actually tried it,
though.
