I wouldn't drag it myself, man is THAT going to be hard to get the car moving with the back tires sliding along. I don't think any 'damage' per se would be encountered, well, until the slack in the chain came up and the front bumper/attachment was ripped off!
Crank with the starter and drive is the only method I'd use. Yeah, it IS a bear pulling the dang trans on mine. I would go to extremes to avoid it if possible.
