Its one of those things that can work in theory but not very practical or economically feasible. Say a starter draws 500 amps at 12 volts DC = 6000 watts. At 120 volts thats 50 amps assuming an AC starter motor hugeeeeeeee enough for such a high torque requirement and many more initial start up load amps.....If you wanna leave the DC starting motor you have to rectify the AC and thats more inefficiency and heat losses.....
