Electrical engineer here. I’m willing to bet that the QC’s 12V jack is surface-mounted to the circuit board and probably looks like this:
If that’s the case, then you would have to de-solder and remove the old jack, make sure the jack you’re suggesting can even fit in the tiny space allotted for it, then manually solder jumper wires to the board.
Can it be done? Maaaaaaybe.
Should it be done? NOOOOOOOOOooooooo.
Way more trouble than it’s worth, plus you can forget about getting any kind of repair / replacement done under warranty.

@DiffractionCircuit Thank you for the great explanation! I also thought that replacing the 12V jack could be risky and might cause issues with repairs or warranty. As you mentioned, desoldering and adding jumper wires seem like a significant risk. This method looks too complicated and could ultimately create bigger problems, and I completely agree with you on that.
I’ve decided to give up on securing the 12V plug. Thanks again!
