Who cares? It's his car and he can build it like he wants. If it doesn't meet your "standard" to call it a T/A tribute then that's your opinion, but the "rules" on tribute cars are pretty loose so it doesn't really matter does it?
Personally I'd like to see it with a T/A hood and ducktail rear spoiler. The T/A hood would have to be custom though.
Showcars out of Canada makes a bolt on and a bond-on version of the T/A scoop.

And yes, I know that Showcars does not have the greatest business reputation. However, I have bought stuff from them through eBay and other than a long ship time (it's coming from Canada) I didn't have any issues with getting the reproduction ducktail spoiler they also sell. For me the additional buyer protections that eBay and PayPal offer made it worth the risk, if something went sideways PayPal has pretty strong buyer protections.
