You know, I think the speeder is being appropriately crushed. The full weight of the AT-AT is not going on it. It's not jumping on it. They just sort of bring the one leg down from a certain number of feet up. The canopy would be crushed for sure, and it is, but I don't think it would sustain too much more damage than it already does in the film. No pancaking, anyway.
Just a thought. ;)
