Here is another thought: The name 'Rainbow Power'. Now, ask yourself this: How does the power of the Elements of Harmony manifest itself? As a rainbow. So 'Rainbow Power' really does have the feel of something intended to reference the show's continuity and mythos.

Maybe they will all be imbued with their element's power, triggering this physical transformation. As well as being able to use their Element without actually wearing it, it may also lead to them manifesting special abilities associated with that Element's nature. Examples could be healing for Fluttershy and a lie-detector sense for Applejack.
