Converting a torsion axle trailer to a trailer with a Timbren Axle-Less Trailer Suspension System has been done before and most people who have done this really prefer the smoother ride and increased ground clearance.

Timbren Axle-Less trailer suspension system is a great alternative to torsion axles. While both systems allow either side of the trailer's suspension to operate independently, only Axle-Less suspensions are actually separate units. Torsion axles still require a bar that spans the bottom of your trailer, whereas The Timbren system can eliminate the need for a thru axle - giving you the same amount of ground clearance from the front of your trailer to the rear. It also allows Axle-Less suspensions to fit any trailer width - unlike torsion axles, which have to be fitted to an exact frame width.

Axle-Less suspensions operate in a smoother, less stressful manner than torsion axles. Torsion axles use a twisting motion, where the bar inside the axle tube rolls against rubber cords or a rubber wall to create compression and resistance. The up-and-down motion of the main spring and the side-to-side motion of the rebound spring in the Timbren Axle-Less suspension work together to provide smooth, consistent compression - with no twisting - that results in a better ride and less stress on the suspension's components.

Since your trailer will be about 1,600 lbs when fully loaded you would want a Timbren Axle-Less Trailer Suspension System # A20RS440. This systems has a capacity of 2,000 lbs and work better for your setup than the # A12RS440 that you referenced as it has a lower capacity than you would need.
