It will be possible in the next versoin of R, and soon in "R-devel" --

 myhcl <- hclust(..........)
 myd <- as.dendrogram(myhcl)

i.e. working with the dendrogram (and its plot method) rather than with the original "hclust" object and its much less flexible plotting method.

Since the needed changes only need R-code changes, you can ask me "off line" and I'll send you the R code needed.
