Here's a rough idea of the Group Badge I came up with earlier this morning for the GB I had in mind..
Mine was little different than yours, in that I was gonna make it modern jets (Meaning post-Cold War only)... Wanted to keep away from cross-overs that way, like when the F4U-4/5 was being redesignated as the AU-1 Corsair and AD Skyraider becoming the A-1 and grey over white vs overall Dark Sea Blue...
Putting the WW2 birds into modern grey isn't something I'd considered...
If ya want, I can tweak this badge a bit more to fit your build, Sparrow..
That said, I'll jump in with an F/A 18 and/or the F-4C Phantom. Which depends on which kit has the most parts left in the box, as I have a tendancy to rob jet kits of interesting detail parts for WW2 birds, lol...
