Well one idea is:

ggplot(diamonds, aes(x = price)) + geom_density(aes(min = -..density.., adjust= 0.5),fill="grey50", colour=NA) + facet_grid(. ~ cut) + coord_flip()

which looks like it would naturally fit with a boxplot overlaid on top of it. However, it's currently not possible because the boxplot is parameterised so that it is always horizontal, while the density is vertical - in the above example I have flipped the coordinate system, but that flips both density plot and boxplot.
