After very careful consideration, I decided that: Top Gun is more an action/adventure movie than a war movie, in the classic sense, and you said as much yourself... I also thought about, if F-14s were your main focus, The Final Countdown would work, but I dismissed that one as well, since its focus is time-travel, rather than the Second World War, which puts it into the Sci-Fi category.
So, overall, I'd have to say "no" to both Top Gun and The Final Countdown. If you were set on getting an F-14 diorama built, I'm sorry. Those two movies are the only ones I'm aware of that featured Tomcats in combat, but the genre is just this side of wrong...
Sorry, man...
