The horse has bolted of course, still you may benefit with half your connection and others may stumble upon this thread.
After reading about magnetic USB-C-connectors, I ordered a couple to prevent wear on the USB port. I use my Model-01 at work and at home, so it sees quite a few (dis)connects.
I have, after a year and a half, just gone through the first of those connectors. The glue connecting the magnet to the wire-head disconnected, the connector still works and I imagine it is easily repaired with a drop of glue.
Mine are labelled ‘Essager’. When selecting a cable over on Aliexpress, I spend days comparing one and another. In the end I found out the mechanism is simple, and I think you could order any of them, as long as it has data lines as well as charging wires.
I mention it, because I can’t imagine bending the on-board connector if the USB-C-connector is attached magnetically only.
-edit- Forgot to mention, the on-board USB-connector has hardly seen any wear, and works without a flaw
