I would still like to, at some point, buy a C8 (base model, used) and stick Fiero badges all over it.

All kidding aside, based upon the fact that there has been a not-so-small industry built up around the creation of Trans Am "knockoffs", built on new Camaro platforms, I don't have any trouble believing that some entity will create a latter-day Fiero, based on the C8.
Of course, it will be hellishly expensive, so the original (unstated) purpose of the Fiero will not apply.
Regardless, I'll bet they sell a few of them.
