A cool Idea but the issue I'm seeing with this is that if you prepare your equipment and open the gauze rolls and other supplies before the mission it will stick to the velcro and deteriorate when taking it out.
I'd say lets try the other solutions. I think they might be sufficient already. Especially one of the panels you guys allready made as a prototype: View attachment 5813
I think the one on the bottom right might be already good enough.
