'd probably go more the crack fic route, where Fritz' idea of being nicer to his nephew is to okay Wilhelmine Encke as maitresse en titre (with state pension), which did happen, after all . :), and his idea of being nicer to everyone else is letting Heinrich go to Paris.

Haha, okay, that I could see! That would be awesome: Fritz being "nice" canonically and not involving a 180 from his normal personality.

Was totally thinking of Otto Gebühr and Stalingrad, yes. Ugh. Fucking worst fanboys. I endorse your crackfic idea!
