I'd ask for a speculative Abkhazian air force skin, based on VVS three-color with this roundel on the tail and wings in the same manner as the red star on VVS MiGs:
According to Wikipedia, which is as trustworthy as we think it is...not very...that's the current roundel. This shows the Abkhazian air force camouflage pattern as it looked in the 1992-93 civil war, on an L-39. The Abkhazians were known to operate at least one MiG-21. It's standard VVS three-color with the national insignia shown below. This version of the roundel appears to be taken from their national flag. No one really seems to know what the MiG-21PF they operate actually looks like, though. I'd like to get my paws on a skin using one of these roundels for a potential inclusion of this MiG in a Sacha Andreeva tale when the MiG is released. I've been casting about for a couple years for new story ideas, haven't done one in ages, but the MiG is giving me an idea I might be able to make something fun with.
