One of my concerns was ground clearance, the other concern is center of gravity. If you raise the entire trailer you mess up the dynamics. Two alternatives a skid plate at the rear of the trailer and air shocks/airbag to temporarily raise the trailer, and incidentally improve the suspension.
I have a Dexter axle I may eventually switch to a Flexride which is adjustable.

When I make trailers with rubber torsion axles, Flexiride is all that I buy. The simple splines for adjusting the torsion arm angle is really worth having.
