It would cost such a small amount of money to just replace some of the theming with some theming for whatever Dreamworks IP they wanted to put in place of Woody Woodpecker. The track wouldn't even necessarily have to be painted depending on what they chose to do. Overall, it would probably take less than a month to retheme that coaster (possibly 2 weeks if they wanted it done ASAP) and the cost would be very minimal.
The thing is, even though the cost is minimal, what exactly is the gain? They still have to figure out how to make money from the land. There's a closed shop in the land that I assume they are retheming as the shop is part of the exit to the theater and it was previously themed to Barney. The question is, are they going to leave the tiny bathroom at the back of KidZone Barney themed or will they retheme it?
Until they bother to retheme that bathroom, I wouldn't hold out hope for anything in the rest of the land, long-term.
