The pinout is not completely symmetric:



So if you did that it'd short the 12V to the 3.3V unless you also rearrange the wires as needed.

You can buy those terminals:

Yeah, you really REALLY REALLY need be sure about pin-out when messing with power supplies and cables. They make those connectors only fit one way for good reason. The wrong voltage or wrong kind of polarity (+ or -) often means destroyed hardware. I have a tester just for that and I still get jittery when I plug hardware in the first time.

I make absolutely no guarantees since I can only go off the picture, but the one with black wires does look correct.
