Nope, the motor doesn't get hot. At all. Ever.
I wouldn't see a big advantage to a portable "jump-starter". Those are still just 12V. There's not a hole lot of any 12V heaters that are really that powerful. (Also, it doesn't provide much of an advantage over the existing car 12V battery. Increased AH capacity being the main advantage, I suppose.)
I do have a little 12V portable heater/defroster. It's pretty wimpy, but I suppose better than nothing for a return trip. Wouldn't heat my feet, but could help keep the windshield clear.
