Therefore, as long as the VIN in the FSC matches the VIN in the CIC, and as long as the two private keys match, you're golden. So if you could get the CIC to have the same VIN as the FSC you have access to, in theory it may work.
When you flash an used CIC (loaded with the donor's VIN FSC) with a new FSC of the VIN of your choice in fact you are changing the VIN of that used CIC. When you read a CIC you will see the VIN, but that must be either decoded from the FSC or it is the VIN from the car showing in the CIC screen. A new CIC does not have any FSC loaded, its variable says NOT_EXISTENT.

I don't think that you will see a VIN packet/data in the CIC that it is in a non-encrypted form.
