I think it does looks good, but what we do with these? There are already ones ingame.
You can swap existing graphics with these.
OR
You can ask Kilgore to implement those into the game, as they look better than original ones
So I've made my own versions of those images.
The Desert Combat Armor was made some time ago.
The NCR Combat armor was made recently and it's exactly as original one, but I separated helmet from the armor itself.
Images are attached to this post.
[EDIT]
Unfortunately I have no idea what should be named the file for NCR CA to change it in game.
