My suggestion would be to have an option to combine bank presets and cosmetical presets. When you would load a gear preset you could apply a cosmetic appearance linked to that preset as well.
Example:
You have a full elite tectonic (blood) and a FSOA (blood) on bank preset X.
You have a Inverted Slayer master cape on cosmetic appearance preset Y.
I suggest to have an option to configure the X preset to load the Y preset as well. This would help loading the gear with the preferred cosmetic appearance in an instant. This could be an incent for some people that don't use cosmetic overrides because they have to use another interface to load a different preset.
