Hi there, I don't think the wrong forum is why there's no responses yet, probably most readers aren't sure what the right answer is. I didn't see your post before, probably been too busy working on the wiki setup these last few days.
In anycase, I'll move this thread for you to the general skinning forum to see if that's of any help.
And my own attempt to find an answer... It sounds like one approach to this might be to try to mirror the insignia on the right cowling manually. The best way to try this will probably be to put that insignia on it's own layer, and do the mirroring there. Depending on the direction the insignia is facing, you'd either need a flip horizontal or flip vertical command on just that selected layer containing the right side insignia.
Hope this helps out, if not post back and I'll take another look at it.
