Not interesting.. You could add a generator and electric motors, but then you basically have a bad double conversion and extra weight. You can strip out the motor, but then you basically are near building a new car anyway. Everything engineered is a series of well-weighted compromises towards a optimum. Adding as a after thought a electric option to a gasoline car, is going to be a bad compromise. Always. If you want a good compromise, build one from scratch (just reusing chassis and gears) or buy one that is designed with this in mind.
