If the material used in the ramp, and the material you use for the supports, is up to the task, that's an idea.
The deck of the trailer will get closer to the ground when you load up and the springs compress. Make sure you leave enough room between your supports and the ground to account for this, so you can flip the ramps up once you're loaded.
