The stock engine isn't powerful enough to charge a hybrid battery pack and move the car down the road. Especially when you factor in the added weight of that whole system. Besides that, idk how you would fit all that into the car without removing the engine
No need to re-invent the wheel. If you want a hybrid then get a hybrid, you want an EV then get an EV. They're churning them out everyday. There's only so many Model A's and they aren't making anymore of them. The hot rod guys are already bad enough chopping these things up and shoving chevy engines in them
