Interesting idea… I’m not advanced enough to know how hard this would be…
The guts of the port, the metal part has fallen anwy and there is nothing to plug into any more.
It sounds like you just need to take off the old part and put on a new one. It is a pretty cheap and easy fix, the hardest part would be that you have to keep your hands steady.
I would love to do that chap. I have it apart but Anker won’t supply the part.
I asked but they said they don’t supply parts.
Have you got a good pc repair shop near you? Or equivalent to Maplin etc.
A micro usb port is quite standard, you could buy it from amazon.
