Yep, but they weren't going to win globally, though locally we'd likely have some of the following, depending on the point in time where the assassination happens:
German version of Hirohito, only it wasn't a monarchy, so likely the new dear leader would be a figurehead in a western puppet government, kinda similar to how it really happened, but without apologies, without reparations, without big trials and with formal and aesthetic preservation of the German Empire, and of course they'd be known for nice cartoons, cool language and really weird engineering (OK, this part happened irl, so nvm) ;
German version of Atatürk, with his NSDAP 2.0 rebranded (same as with Kemalists being slightly rebranded Young Turks), which is totally not NSDAP, and lots of stupid people would praise them for fixing the mistakes of previous incompetent and criminal leaders (including Holocaust, which was committed by a totally different party and totally different state, but still didn't happen, and if it happened, then they deserved it, and we'll do it again), ah, and of course the German Empire keeping Silesia, East Prussia, northern Schleswig and maybe even Austria, and continuing analogies, I'd expect Sudetes and Danzig and whatever too ;
Something similar to the "Fatherland" movie, not in the sense of Nazis winning, but in the sense of society and, again, crimes against humanity ;
Some peace without WWII starting or around early 1942, highly improbable seeing how eager they were to do it all, but - then maybe a very slow Mexican duel of a Cold War.
