A battery pack with that many KWh would let me do most of my trips without firing up the ICE, assuming it can provide enough amps.

As the owner of a plug-in mild hybrid, I can tell you setup #3 will prove inefficient on short trips. The ICE ought to be moderately loaded or off for best efficiency, but with heavy assist, it's just going to be lightly loaded all the time.

I like the option of driving the rear diff with your electric motor. Alternately, delete the rear diff and drive one rear CV axle with your motor if that would get you a more appropriate motor speed.
