Apprently they are rare- I have a friend that made a custom PP2a3 that could be converted to PP45 (I already have an SET 45 from him which is great- it is an awesome tube), so I am curious how it would sound as well. I can only guess that if the reason for wanting more power from the 45 is why the reason to creat a PP version, at that point people might be thinking a 300B instead at 8+ watts, hence the popularity of those amps. It would be great though, to see more 'all-out' 45 PP designs...
