I sincerely hope that doesn't happen anytime soon, the park has many things on their plate that they need to change (Movietown/Old Country, replacing Rolling Thunder, filling the old Safari Discoveries area, the old paintball building, etc.) before touching the fort.
In addition, demolishing the fort would put two important family rides, the Skyride and Runaway Mine Train, at risk. With Skyride being the only in-park transportation, and Runaway Mine Train being the best family coaster in the park now that RT is gone, the loss of these 2 rides would be potentially devastating to the park for families.
