Uhh....why though?
With modern jets, you can't even see the pilot's skin color 99,9% of the time. Not even with pilot body enabled, Because they have their whole body covered. Not even in external view 98% of the time, assuming they take their visor off when the canopy is open, otherwise the visor completely covers their face. Rest of the time, you won't be seeing any skin on your pilot model, so the whole point is rather pointless.
I get that you may want to feel represented, but you're basically asking them to make a seperate pilot model just so you could stare at it during external view
