An interesting idea for the skin series would be to make them all one skin but cycle through the three variants as the float of the skin changes. This could also open the possibility to interesting mixtures of colours and make the skin unique.

For example, the skin might only be all purple (Revered) for the lowest FN floats with it being all gold (Sun) somewhere in the middle and the skin being completely silver (Kanbu) with the highest BS floats. There could also be rare combinations such as black and gold, blue and purple and silver and green which could appear when the skin is at the float for the corresponding colour.
