There's already a 325th skin for the Pony D, 1 for the Pony B, 1 for the P-47 D11 and one for the P-40E. Are you saying you want more skins for each of these 4? We are already limited to 15 skins per aircraft and making the same style paint schemes over and over takes away from many of the other schemes that could be painted.
There's already 2 D mustang skins that are virtually identical. If anything HTC could implement a system that gives you multiple base skins with the ability to change slight markings for each of those skins (Tail Code, Serial Number, Nose Art, ect...). That would allow us to do atleast 15 different base squadron schemes with almost unlimited variations.
I'd prefer this type of system due to the limitations we already have on the amount of skins that can be made per each aircraft. The skinners do amazing jobs on the skins they make but making virtually identical skins for the same aircraft takes away from other skins that could be made to give a wider variety. It would also give us the ability to represent as many squadrons as possible in the process. Skins shouldn't just be made to fill a void.
