No this won't work. Despite the card number and expiry date being the same, the magnetic stripe data will be different. The service code on the magnetic stripe of an EMV card is different from that on a non-EMV card. (This is how a EMV terminal knows when you swipe an EMV card and prompts you to use the chip reader instead). As well, the discretionary data field is likely different as issuers use that field as a way of validating the version of the card being used.
