You're pushing a rock uphill, Pat. I'm surprised they're not asking for two layers of 5/8" drywall on each side. Google tumescent paints and see if that works for you and the AHJ.

The only person whose opinion counts is the inspector who will be signing off on your project. There are products out there, but inspectors are not required to approve their use. The standard way of shooting you down is to approval it conditionally, and the condition is that you do a full scale UL test with your intended construction.
Any way, it can't hurt to ask.
This is what the NY State code has to say about the code enforcement official: "=A7104.11 Alternate materials, design and methods of construction and equipment. The provisions of this code are not intended to prevent the installation of any material or to prohibit any design or method of construction not specifically prescribed by this code, provided that any such alternative has been approved. An alternative material, design or method of construction shall be approved where the State Fire Prevention and Building Code Council finds that the proposed design is satisfactory and complies with the intent of the provisions of this code, and that the material, method or work offered is, for the purpose intended, at least the equivalent of that prescribed in this code in quality, strength, effectiveness, fire resistance, durability and safety."
