Um 'Happy and Glorious' and 'Whale has Wings' makes two threads. As for the rest take a trawl though the first couple of pages in post 1900.
A few days ago when commenting on another thread I counted 7 threads on page 1 of post 1900 that either had the Nazis or a watered down version of Nazis doing better or asking how it could be done. I
didn't include those threads that had Germans doing better in WW1 as a starting point.
Happy and Glorious was originally started after more than a year of watching countless threads being posted about German super ships, super planes, Manstein being a genius, Rommel winning everywhere, what if Barbarossa succeeded and of course what if Hitler was a little less crazy

etc.
I wondered where the Allied threads were and more specifically British stuff. True some existed but they were thin on the ground in comparison and few did more than ask a simple what if and then vanished among the panzers, U boats and Bismarck surviving threads. There were few Allied storylines around. Now I can see two and Sharlin has tried something original with the Franco-Japanese naval war.
