I think it's probably a straight swap. I'll tell you why. I looked at a face-lift car that had the old lights and wrong bumper. Figured out that the guy was buying write-off cars and fixing them up. He'd clearly put the wrong lights and bumper on because that's what was available to him at the right price.
Can't guarantee it but I bet they just work.
My question would be, why bother? An FR bumper, I get it, but to be honest I think the older lights look better than the face-lift ones.
