Personally, A-7E and A-6E TRAM to round out the late 70s/80s/early 90s aesthetic for the Tomcat, Hornet, and Harrier. Then update the existing naval aircraft/helicopter models that still need it, Then start turning out AI models for the support aircraft that aren't in game yet (C-2A, KA-6, EA-6, UH-46, EKA-3, etc.) and the ships that aren't in game yet (CV-63 CVN-65, FF-1052, DDG-51, DD-963, DDG-993, DDG-2, DDG-37, CG-16, CG-26, CGN-36, CGN-38, The Pre VLS CG-47s, BB-61, the whole bloody [soviet] fleet). With those you are completely set for the 80s through the 2000s, and large portions of the previous eras. From, there, just start working it back for player modules. A-4E and M, F-4B/J/S. A-6E and A, A-7A/B, F-8.
Not that I've thought about this or anything.
