Paint the Night parade

I highly doubt it because it simply is not meant for WDW. Like how Festival of Fantasy wouldn't work at DL and how Soundsational wouldn't work at WDW. Plus, WDW still has Main St Electrical which appeals to an older audience due to the nostalgic factor. DL has more of a younger audience who is open to new things.

I think there's a possibility it might, but not at main street. I think if it would ever appear at WDW, it would be at Hollywood studios.
