Hi Jaime,
I'll look into lengthening it to reach the stem.
Not at all easy, I'm afraid. Are you looking for the cluster-band sort of notation, or would individual clusters per stem suffice (like Cowell, for example)? Possibly the latter would be easier to implement.

P.S. A while ago, there was a really interesting thread about contemporary notation. See this message: http://www.mail-archive.com/lilypond-user%40gnu.org/msg95570.html . I don't know if the poster has made these functions available, but number 15 looks similar to your request.
