Replacing headband on edition xx

So I sold my HiFiMan Edition XX to a friend and they broke the headband. Now she wants to replace it with a hammock style so I looked on Hifimans website and they have a couple. The hybrid looks perfect, but wasn’t sure if I can just swap it out. Contacted HiFiMan and boy was that an issue. Days of back and forth with no answer other than sending mine back and paying $200 for the repair. Can anyone tell me if you can actually replace the headband? It looks like you can, but I want to know for sure before ordering this hybrid headband.

Assuming this screw here is what broke, why not just replace that?

Pulling out the outer plastic covers should tell you more.
