I won't base a skin on just a profile, skin or model, particularly a Soviet one. A lot of skins in other games are based on out of date info or are just made up. AH skins have to have to be accurate and must be backed with decent source material, usually RL photos.
Profiles of Soviet aircraft are frequently inaccurate or are sometimes even total figments of the artist's imagination. During the Cold War it was hard for Western book authors to get good source material on Soviet WW2 stuff so sometimes artists just guessed WRT colours etc. Since the 80s though a lot more has become know about the subject in the West.
The Yak-9T entered service just before the VVS changed from their green/black scheme to their grey/grey one. During the early war years in winter the green and black aircraft were often whitewashed, but in the later years grey aircraft rarely were, if ever. Partly this was because there was a lot less chance of LW attacks on Soviet airfields during the later years of the war. Also the grey scheme worked well in the air during winter.
I've looked at a lot of photos of VVS aircraft and the only ones of the AH planeset I have seen in the winter scheme are the Yak-7, Il-2, I-16 and a few western types used by the Soviets. There is also a photo of an La-5FN in white, but it is a test example and not a front line aircraft.
If you can find a WW2 photo of a Yak-9T in white, I'd be glad to skin it.
