That's not the way modern MBA's think, everything is an opportunity to establish or grow a brand to increase long-term revenue. They can't license "haunted hotel" to Mattel. Even branding it as Rapusal's Tower Climb would be more "marketable."
As noted, ToT is probably safe for the meantime because the focus is on SWL/TSL. If Viacom ever gets any of their Twilight Zone projects out of "turn-around" (not likely), it may either help or hinder the long-term future of the TZ-branded ToT; but no product sure doesn't help.
I love ToT as is, and my son became a TZ fan because of the ride (but that doesn't help Disney's bottom line), but predictions should be made from a sales perspective — executive officers almost always work their way up through sales — not a fan perspective. They know they aren't going to going to lose guests by re-branding.
