OK. Having been thinking it would be piratey due to the original teasers (Walk The Plank/ Shiver Me Timbers were my fun names of personal choice) years ago, now they may it seems be going for The Wicker Man and siting it in Gloomy Wood location wise I have two out there but possible ideas.
1. original teasers did link it to old log flume- could it still have water, still on theme because water puts out...
2. Fire. Yes, I'm thinking, long shot but possible, could be a world first and have fire. On a wooden coaster (not as crazy as it sounds as timber can be fireproofed and distances made safe etc, surely very possible with what we now know, maybe even a fire tunnel like stunt rider props for coasters hehe)
Blackpool wowed people with Valhalla, could it be slightly dark ride plus coasterish?
Slightly out there theory but in The Wicker Man
"The villagers force Howie inside a giant wicker man statue, set it ablaze and surround it" from https://en.wikipedia.org/wiki/The_Wicker_Man#Plot
So maybe fire then a splashdown to 'put it out'
And re the 'isn't it a family ride' factor, horror has influenced lots of rides such as Saw, Hex, Thirteen, Ghost Train... and it might be kind of teen-upwards level family target, so can see it being along those lines. Horror's not so horrific in 2017 for many, for some yes, but it's somewhat mainstream now from computer and board games to TV, films and of course theme parks.
