reskin

To replace or repair the skin of a motor vehicle, aircraft, etc., especially so as to market the same car under different brands

A row of original, large and life-expired MoD 'wriggly tin' Nissen huts close to the Rail Live entrance haven't simply been reskinned, they have been replaced with new, modern equivalents to the original design.

To change the skin, or visual appearance, of an application or a video game character etc.

The editor can be reskinned. In other words, the color scheme and look and feel of the buttons can be changed.

Something that uses the exact same model as something else, but has superficial differences such as textures.

The result would be a reskin of an old game instead of an interesting new game.
