Cluster function

[Mark Knoop]

Has anyone had success making clusters such as in the attached image?
This is not possible with the builtin \makeClusters function which
removes stems, beams, accidentals, etc. 

Ideally code something like

<cis' ais''>8. \cluster <c' ais''>8. 

to produce this example. 

If not, any ideas as to where to start with such a function? I suppose
I just need to get the positions of the two noteheads and draw a thick
line in between.

Many thanks,

Mark
