I think it makes sense from your side of the equation to put a 9 inch in it and copy the 4 link from the COPOs since that's what you are familiar with, it works, and it's already legal. But if a guy just wanted to do minor fab work with the cage and bolt in front suspension, is there a path for running the car with the OEM transmission and rear end? I feel like just because the rule book says you can put a 9 inch in the car if it was built after 2008, you shouldn't be forced to if you don't want to.
Let's not forget that a Corvette can swap out to a solid rear axle which is obviously a long way from the way they came from the factory, no one seems to be concerned about that deviating from original. NHRA approved that a long time ago, how is this any different? On that same subject, a Corvette legally be run with the original IRS if they so choose but I doubt anyone would.

Jim, I think you forgot to mention that the Corvette can be swapped out to a GENERAL MOTORS solid rear axle, but not a Ford, Mopar, Toyota, or any other manufacturers solid rear end. That was done more for safety than anything else, as the half shafts of the IRS were key to help keep the wheels positioned properly, as the older Corvette IRS system did not have upper control arms. So, if the axle or an axle U Joint was to break, the wheel was free to flop around, and likely cause a crash.
