Question Can I use a pcie cable in the cpu slot (modular psu)?

[Starcruiser]

To start with, I know everyone's first thought will be "this is a bad idea" but I mostly want to know if it is Theoretically possible.

I have an EVGA 650 GQ 80+ gold semi modular power supply. Only the main 24 pin atx connector is hard wired.
The power supply has 2 slots for a cpu cable, but only includes one cable. It does, however, have 2 6+2 cables.
Looking at the atx specifications it's possible for the cable to fit in the cpu slot on the motherboard, but the +12v and ground are flipped in the specification.

However, I assume this is because of the wiring in the psu and not the cable. From a visual inspection, the cables appear to be wired the same way. The more I think about it, the more it seems possible that I could use a pcie cable in place of the missing second cpu cable.

Short answer - Do not do this.
Long answer - Which parts would you like to see go up in smoke?

This is why it's all theoretical. I'm most certainly not going to do this, but I'm curious if it's possible.

I well aware that the second cpu slot is optional on my new motherboard.

I have the same PSU and it included 2 cpu power cables if short one contact EVGA
