Power bus and wireless expansion cards

Does anyone know if it would be feasible to have slightly more power output on the USB bus? I’ve kinda moved to using my framework as a laptop/charging hub. I put a USB multimeter on it but forgot what it could output (full disclosure: this post is a sticky to remind me)

I know there are a bajillion expansion card ideas, how far had having another another wifi chipset with something like a BNC(?) connecter? Would the expansion card interface be able to handle the mechanical loads? Taking another tangent my favourite part of my old T420 was the cellular compatibility, possible?
