can you think of a Yin-Yang (by color: Black and White, or by element: Fire and Water) Gokai Change like this one (example):

Yin-Yang Gokai Change

 * Gokai Red - GoggleBlack, GingaRed
 * Gokai Blue - Big One, GingaBlue
 * Gokai Yellow - NinjaBlack, Princess Shinken Red
 * Gokai Green - AbareKiller, Blue Dolphin (male version)
 * Gokai Pink - Go-On Black, MagiRed (female version)
 * Gokai Silver - KibaRanger, Gosei Blue

Since the concept of Yin-Yang (陰陽, Onmyo) tells about opposites by color (black and white, red and blue) and/or element (fire and water). For instance here, Gokai Red changes to GoggleBlack followed by Gokai Blue changing to Big One.
