There are some out there already. Italeri and Revell package a lot of the display schemes but aftermarket decal sets can transform any manufacturer's kits into show airframes. The 2015 (Battle of Britain 75th Anniversary) scheme for a Typhoon is available from Xtradecal (Hannants). This was used in a synchro pair with one of the BBMF Spitfires (which one depended on availability but I aim to build it with P7350 at some point - a good project for the RAF 100 Gift set).
The Polish airforce painted up their display MiG 27 with the 303 Squadron badge on top which looked impressive and the Greek and Tiger meet schemes can be really impressive - choose an airframe and see what you can find. Another company (can't recall which) produces decal sets for the entire American Air Museum collection at Duxford so there are other options. There are Tornado anniversary schemes (though Airfix haven't released this in a while and it is considered pretty tired). Airfix used to do a BBMF set (Lancaster, Spit II and XIX).Airfix don't have many current models in their lineup (no F16, F/A-18, Chinook and similar) so you might need to look elsewhere for the really fancy schemes.
Also non-UK display teams use different aircraft which Airfix don't make (Alpha Jet (Patrouille De France), CASA Aviojet (Patrulla Agulla), F-16 (Thunderbirds), F-18 (Blue Angels) etc.). Though Airfix did previously release the Magister in Patrouille colours.
There are also loads of Mustangs on the display circuit in varied colours and the Airfix Vampire has a UK based display option in one of its releases. Same with other American Warbirds.And don't forget XH558 if you want to tackle a Vulcan which can be done straight from the box.
So, there are plenty of options out there but you need to look at somewhere like Hannants to find the decals.
