The requirements I laid out for mine were more of a theoretical wants list. I highly doubt a one true perfect revolver will ever be built. I am immensely happy with my 5" Model 29 for an overall piece. The thread is also an opportunity for others to discuss what their idea for a PP revolver would be/ is.
Personally if starting over, I could be totally happy with a .44 special. That said, I shoot a bunch of .44 mag, so I just use mag brass and download to special levels. Just having one type of brass, and never having to readjust the dies works for me.
A nice skinny barreled .44 special could certainly make the list as a top contender for "perfection". The .44 special is a very capable and very underrated cartridge these days.
