I dunno... I'm not dismissing the idea, as it has merit... there's just some things I don't like about this "pick your own path" style of skin "fix".
For instance, I don't just pick a skin for ME, I pick a skin in the hopes that others will see it too. By doing it this way, that's no longer garunteed.
Also, since other people will be picking skins I won't have, it'll actually increase the number of planes I see that look no different than default. In other words, it strikes me that by going this route, yes, you can choose what YOU see for the plane YOU fly, but chances are, other people won't see it, and you'll see a lot more default skins and less variety than there is now..
Just MHO.
