You can customize the function that computes the summary statistics,
and that seems like the only reasonable entry-point for you. A simple
example:

bwplot(voice.part ~ height, data = singer,
       stats = function(...) {
           ans <- boxplot.stats(...)
           str(ans)
           ans
       })

You will need to figure out how you will "dump" the parts you want.
