Nico - That's a pretty restricted list there, after all, each nation has its own fighter, bomber AND assault class, even several of them, not to mention "bonuses". I'm pretty sure anyone'd kill for an Su-47 Berkut flight, then again, an Su-37 Terminator or a MiG-35 1.42 MAPO-MFI would be just as nice (especially the latter as it's stealth-capable).
To expand on your list, from fighters, bombers and assaults to specials:
I.E.:
USNAF - F-14 Tomcat, F-117 Nighthawk, A-10 Warthog II or F-4D Phantom II, YF-23 ATF or (X)F-35 JSF
France - Rafale or Mirage F.1, Mirage 2000, Mirage IV, Avro Vulcan or Avro Arrow (maybe Canada'd be involved?)
UK/DE/IT - Panavia Tornado ADV, Panavia Tornado IDS, Hawker Harrier II VTOL, special... maybe a German MiG-29K?
Russia - MiG-31 Foxhound or MiG-29K Fulcrum, Su-34 Platypus, Su-39 Frogfoot (the next assault plane since the Warthog

), MiG-35 MAPO-MFI OR Su-47 Berkut OR Su-37 Terminator OR Yak-141 Freestyle VTOL
Sweden - Saab JAS-39 Gripen, Saab J-35 Draken, Saab JA37 Viggen, ... no specials so far (not too sure on their classes either)
...and we could go on and on and on like this.
But, no models? I'm pretty sure there's a depot SOMEWHERE in all those pentabytes around the internet!
No Fredders? I'm pretty sure I could rally up a few people eager to work.
No time? ...okay, so you got me there.

But an idea / plan / setup would be nice too! Not to mention you'd be a big help being around, I for one am getting skybox trouble out of this current little "demo".
Trashman - Yeah, I'm a Croat too, nice to see I'm not the only one around
