I've recently been diagnosed with lateral epicondylitis (tennis elbow), which really sucks right at the start of summer😞

My physio has advised that the elbow needs to be progressively loaded as part of the recovery process and suggested that, alongside my rehab exercises, I can continue windsurfing, just at a reduced frequency and intensity.
I mainly wind foil using a waist harness, but I'm considering switching to a Liberty (hip) harness. My thinking is that the lower hook position might help take some additional load off my arms and reduce strain on the injured elbow. I'm also planning to experiment with harness line positions to see if I can reduce the load on the affected arm.
So, a couple of questions...
Has anyone recently purchased a Liberty harness from an Australian dealer, or would I need to order one from overseas?
Are there any similar harnesses available with a lower hook position?
Has anyone dealt with tennis elbow while windsurfing and found that changing harness type or setup made a noticeable difference?

My goal here is to keep getting out on the water over summer without setting back the recovery
