This is why skinning is more suitable for parts such as interior.
Notice that how many small complicated and inter locking fixings there are for the interior?
Something like this is near impossible to hand make out of carbon or FRP which is why skinning the original part is the best solution to ensure best possible fixings.
Some parts may even interlock so lining up is important. By skinning you do not change any of these aspects.
Had parts like this be made purely out of carbon you'd either have to fabricate or come up with your own method of fixing or risk it flapping or moving about.
Things you must know about skinning
It does make the surface stand out more than normal by approximately 2-5mm +/-
Overlaying carbon to your parts will make the part much more rigid and harder so some flexibility will be lost
