The most admirable aspect of a company like GCI is the designer's ability to create nostalgic re-imaginings of classic elements, but using them in such a way that they stay true to the integrity of wooden coasters. Elements like ninety-degree banking and reverse banking are unobtrusive, exuding a respect toward classic wooden coasters. These and other modern elements/updates comfortably enhance the forces that are inherent in woodies, like strong laterals. However, by suggesting things like a vertical drop and an inline roll, one is essentially just reworking elements of steel coasters into wooden coasters, which doesn't necessarily pay proper consideration to the conventions of classic woodies.
A dark ride section on a modern wooden coaster would be interesting. For example, a re-imagining of something like Lost Coaster of Superstition Mountain. Though, not necessarily a two-car train with an elevator lift (although, that would certainly draw interest), but more in principle. Just a simple meandering through a few scenes before the lift hill would be really cool.
