The Germans start with: Rundstedt, Leeb, Bock, Guderian and Hoepner.
On the Place Builds Phase of Winter 1940, they add: Hoth, Weichs, Leeb and Kleist.
On the Place Builds Phase of Winter 1941, if they have not yet won the war, Hitler removed less 'reliable' generals Guderian, Hoepner, Leeb and Bock and add Manstein, Paulus and Kluge.
On the place Builds Phase of Winter 1942, if they have not yet won the war, Hoth is removed and Kesslering and Model are added.
On the Place Builds phase of Winter 1943, if they have not won the war, Manstein is removed and Manteuffel and Dietrich are added.
Once a German Mech unit is landed in North Africa, Rommel is placed with the unit on the Place Builds Phase.
That is the Germans leadership moves for example. We played around with the idea of air leaders - but did not add them yet - but perhaps certain air leaders could give a boost to combat like Richtofen gets a re-roll for ground support, Harris gets re-roll for strategic bombing, etc.
We did add something similer for German subs. The Germans start with three sub 'aces' (Kretschmer, Luth, and Prien) that give them Sub attack re-rolls. Something similar could be considered for air-leaders - but have not played with the ideas yet.
What are you thinking as far as air leaders go?
