2. PZ=0 -> Use MUA to upgrade to PP

I don't want to end up using GPU to upgrade to PP.

If I use miles today to upgrade to PP, and keep monitoring PZ space, can I later on cancel/refund my miles back to W fare if I see PZ>0, and apply GPU to get to Polaris?
Has anybody successfully called MPSC to "swap" the GPU out "after the fact" for miles if only the PP leg clears?

I have done so back in the pmUA days to swap out a SWU for a CR-1 when the domestic leg clears and the international did not....
