I guess the only thing to consider is whether or not the hinge pin springs are still in place; without them, pulling the pins would be the quickest way to get the doors off if they're loose. If the springs are intact, you could just unbolt the hinges from the doors so you don't have to deal with the spring potentially launching itself at you. I can confirm that if you have manual locks and windows, the doors are pretty light and one person can move them around pretty easily.
If it's an option, you should pick up one of these:
