Need Tech Help. Neon Auto Trans Question.

Hoping somebody that works on automatic transmissions can help me out a bit. My Nephew just bought a 97 Neon with an automatic transmission a couple of weeks ago. Less than a week after he bought it the timing belt broke. He needs to haul it about 90 miles back home to work on it & get it running again. He has a tow bar but we know you're not supposed to flat tow these cars with an automatic trans & I'm guessing it's because of possible damage with the pump not running.

We were discussing this on the phone & I had an idea. Now I need a tech to tell me if there's a chance it would work. Could he plumb an electric fuel pump in the line to the in-radiator transmission cooler & use it to circulate the trans fluid? Would this lube the trans internals enough to let him tow it home, maybe at a reduced speed or something? Any chance?
