Space Mountain Ghost Galaxy coming to Walt Disney World?

Disney Parks Blog  just announced two new Halloween themed overlays coming to The Magic Kingdom during Mickey's Not So Scary Halloween Party. The first is a new spooky experience at Pirates of the Caribbean including a new interactive experience where guests join the Pirates looking for a new character named Gunpowder Pete.
The second announcement is a new soundtrack and effects for Space Mountain for the Halloween season.  It can be speculated that the popular Ghost Galaxy overlay at Disneyland's version of Space Mountain will be duplicated in Florida. Ghost Galaxy features a loose narrative, scary soundtrack, and jump scare projections. No additional information regarding either update is currently available.

Seasonal overlays have been popular for years in Disneyland in the form of Christmas themed Small World overlay, and the hugely popular Nightmare Before Christmas themed Haunted Mansion Holiday.  Walt Disney World's first ever overlay was Jingle Cruise adding holiday jokes and props to the Adventureland classic ride, The Jungle Cruise. So why hasn't the Florida park had the same guest opportunities as California's Disneyland? The answer may be in the makeup of the guests themselves.  While Walt Disney World is the number one international tourist destination in the world, Disneyland caters to a more local clientele.  Whereas Disneyland guests may come to the park multiple times a year, typical non-Florida resident guests and international guests my only be able to visit Walt Disney World once in their lifetime.  Imagineers may be less likely to change the experiences for those who want to experience the original attractions.
That may be changing with the two new Halloween experiences and the announced addition of the Mad Tea Party, also transplanted from Disneyland.  One can assume that, based on feedback, more temporary changes may be on the horizon, especially with the 50th Anniversary just around the corner in 2021.  Could the EleTRONica experience be on the way for the opening of the new TRON coaster in Tomorrowland?  Here's hoping!
