Navy sinks old concrete carriers in the Gulf of Mexico already, for this exact reason (artificial reef). i remember this happening at least 20+ years ago... it's not as new novel idea. Florida also uses shell material as aggregate in concrete already.

I'm not sure about the "concrete" part, but the final Essex class carrier, USS Oriskany, was sunk off Florida to form an artificial reef, the first US naval ship for which this was done, just about 20 years ago.
