Might help a little bit, by heatsinking the contacts better, but the problem is the contact resistance, not the wire resistance. The connector itself dangerously heats up.

Or at least I think so? Was that a different 12VHPWR scandal?

Contact resistance is a problem.

Another problem is when the connector is angled, several of the pins may not make contact, shoving all the power through as few as one wire. A common bus would help this but the contact resistance in this case is still bad.

I thought that the contact resistance caused the unbalanced wires, which then overheat alongside the connector, giving the connector’s heat nowhere to go.

I think it's both contact and wire resistance.

It is technically possible to solder a new connector on. LTT did that in a video. https://www.youtube.com/watch?v=WzwrLLg1RR4
