Curious how so?
It doesn't solve the problem, just ignores the problem and adds multiple iterations of the exact same plane in the hangar screen. Imagine how annoying it would be to scroll through 5 P-51Bs and 7 P-51Ds, identical in every way except the skins options you have?
Then imagine trying to find that one skin you remember, but can't recall the name of it. Going from skin to skin then plane to plane multiple times over.
All the while it doesn't solve the problem of upping the resources the game eats for every skin in the game.
So, as I mentioned I'm sympathetic but this idea simply adds clutter, confusion, and doesn't come up with anything new. Hence it's a horrible idea.
