I also think that it does not make sense to do so much work at this details. I still have to make the painting itself (black and two different camouflage) which then should be used as a second layer under the details, so a lot of graphic work for those textures have also to be made.
Not sure we are on the same page. I am thinking about placing both parts (left and right) on the same texture, but on different parts of it so they will be not symmetric. You can do whatever you want with left and right parts, but still they are same surface. It can be more complicated with Ka-52 model, but you always can increase resolution of the texture and manage UVs to fit everything on it.
