Blink Emission

I'm using a coroutine to make an object blink when I hit it, and that's working fine, but I'm missing one part of the effect, and that's the object's brightness blinking with it.

I'd like to make the object light fully, like it was vertex-lit, or textured with a full-white emission texture.

Right now, I'm leaning towards using a material that's got an emission layer, and trying to toggle between its normal emission texture, and a full-white texture, but I'm unsure if this is the most efficient way of handling this.
