They wouldnt need to review anything, and it wouldnt require any additional resources in the client… It would use existing elements from existing skins. You simply choose how they are applied to your ship (what angle they’re positioned in, Where on the ship they are placed)
It wouldnt require any approval either, since it would only use existing skin elements. You would simply be “remixing” the existing skins. You can take the Skull from the Headhunters skin and combine it with the Glacial Drift Pattern, provided you own both of these skins, for example.
