I do have an option for you but there would be no way to lift your trailer using your existing half torsion axle system as they just don't make anything to allow for this. The only option you have to raise the trailer would be to install a new system with built-in lift like the Timbren Axle-Less Trailer Suspension System part # ASR3500S06 which will retain the same torsion axle design and install in a very similar fashion which you can see in the attached install video. This will be the only option we have for you to raise the trailer.
In order to add new brakes and hub/drums you can use both the Electric Trailer Brake Kit part # AKEBRK-35-SA and the Trailer Hub and Drum Assembly part # AKHD-545-35-EZ-K (2). If the hub/drums you have now use a L68149 inner and L44649 outer bearing then you can just reuse them.
If you would like to know exactly how much it will raise the trailer you can measure from the bottom of the frame to the center of the spindle. That same distance on this system is 7-1/2" so the difference between this and the system you have now will give you the amount of height gained.
