Yes we have. I wrote a funnel into the Drakborgen kickstarter forbidden lands module.
However. It kind of goes against the Core of the game.
The only way to so a funnel properly is to say for example that the village has a problem with a monster and that a dozen villagers are villing to fight it. Who ever comes out alive will be the players characters.
But... it's not made for that game style at all tho.
//edit: the game is a hexcrawl and that is an important aspect of the game. So the funnel might be strange. I can share how I made one later if you want
