I might be in the minority here, but I don’t actually enjoy the blingy skins of later cards. Sometimes I actually most prefer the Iron, Lead or even Default look, but don’t want to be disadvantaged via a lack of augments. One obvious solution is to just give Augments to all loadouts (which I think is a good idea as it’d stop new players from being disadvantaged, even minorly) but it might not be popular with the developers.
So instead, introduce cosmetic loadout slots: your primary loadout dictates everything it does now (appearance, augments and weapons) but you can choose to slot in any card to change the appearance of your outfit and weapon. If it’s not possible to have separate weapons and outfits (and I don’t see why it wouldn’t be) then you can just have one cosmetic loadout slot that overrides the look of your “mechanical” loadout.
So, for instance, I want to take my Bronze card’s augment and weapon set, but then I want to have an Iron outfit and a Default weapon. This could even go so far as to let you choose the skin for each individual weapon, so maybe I want a Silver pistol but a Lead weapon. Customization is fun, right?
