I was thinking last night about a scenario skin idea. For scenarios or FSO or SEA in general, a skin overflow aside from the normal MA skins. These skins could be added by the CMs that are historical to the scenario that might not be currently in the rotation. Or if more than 1 skin of a particular squadron needs to be added.
So if you have 15 skins normally, you have say 5 extra per plane in the SEA arena for CMs to fill with scenario-specific skins loaded in.
