Good and simple idea!
Before doing what you've suggested I've done a measurement with a multimeter, and found it's actually the tip, not the sleeve that loses the electrical contact.
I've started to search for a more complex solution like replacing the barrel connector with a USB-C connector such that I'd power my SBC using USB Power Delivery tech. Seems like quite feasible solution:
- Simple way to get 5V at up to 3A (no IC): https://forum.digikey.com/t/simple-way-t...a-15w/7016
- Robust way with two IC involved: https://fpx.oxplot.com/
