No captured skins allowed. The only real case would be for the 190D, as a number of those were captured on the ground and pilots from some regionality (I don't recall which -- Poland, maybe?) flew them. However, this was 1 flight out of hundreds of thousands of planes involved on all sides. A very small number.
The others were all test planes, captured trophies, etc.... Considering they didn't have He162s anywhere near the Soviet lines I'd be willing to wager that's a post-war captured plane, after Berlin had been over-run. I would say the same about the 163s as well.
None of those are valid for use as skins in AH based on HTC's criteria/requirements.
