I would specifically mention the 1944 assassination. First of all the conditions are way too extreme - the event fires usually when Germany has only a few provinces left. Make conditions like no Moscow, Leningrad, Stalingrad and USA or Britain controlling at least one French coastal province.
If the assassination is successful a military government takes over and Germany can request for peace with the Allies, with appropriate conditions. If the Allies accept Germany disbands much of its army, becomes US puppet (though with event restoring their policies to Paternal Autocrat), and Allies join the war against Soviet Union. Speaking of which, there could be surrender events where USSR surrenders to the Allies (as result of WW3 or Allied intervention in Winter War). Not as harsh as Bitter Peace but something like what the Poles were planning (dividing Russia into a large number of independent buffer states)
