High Fantasy + waterfalls

There is no waterfall tile in the High Fantasy pack, as far as I can see, and I can understand why. 

In default style tiles the water in a pool goes up to the edge of the cliff face, and the water can therefore look like it's falling straight down the face of the cliff and into the pool.  High Fantasy cliffs, on the other hand, end standing back from the edge of the tile, leaving a clear gap between the cliff and the pool.  This visual gap is accentuated if you put a foam event in the usual place.

Has anyone found a way round this?

Thanks.
