A couple of thoughts on that...
One, they could just create an attraction based around David Tennant, who I think is generally the most popular modern Doctor and would serve well to create a more or less "timeless" (please tip your waitresses) attraction.
Two, they could create a multi-Doctor adventure featuring several of them, maybe with the flexibility to rotate in a scene or scenes with a new Doctor every few years if they feel like it. Kind of like the Hall of Presidents.
