I don't understand why you need such thick wire. It really doesn't make sense when you compare to macbook. And X360 is not using that much power, especially the slim.

Get a pair of scissors or a knife and cut open the cable.  You can yank out about 90% of the wires, but make sure that it's plugged in when you do it so you can see if you've pulled out too many.
