sequel (lose the POV)
I would like to see a follow up to this set maybe in a facility underneath Berlin as the Red Army approaches and hundreds of Nazis and local populace are being converted (a wolfenstein esque Hitler with chain guns perhaps), you could have the Red Army fighting them tanks et al for the finale.
Or failing that post war, set in the Soviet bloc or Area 51 or something, as long as a Frankenstein has plenty of subjects to "work" on!
