What are you going to do with a Sankie documentary? It isn't dangerous, Sankies don't tend to be dangerous.
Why don't you do something useful and investigate the downfall of the Northcoast tourism and the effects on those who rely on it. Sankies, bar owners, moto conchos, etc etc etc.
Would seem more interesting, and quite viable. Who wants to see a documentary dedicated to wrinkly old grannies in thongs and the guys they screw. Open it up a bit.
