    This is great and may be an inspiration for me to handle my request from 
    a few weeks ago:

    I'm not sure this might work at all since (like with the noteheads and 
    the stems) through the \magnify the horizontal extent of all objects is 
    different. I think what you'd basically have to do is making the 
    secondary dots transparent (as you do in some instances).
    
    What I would go after is a music function that detects another note head 
    in the same NoteColumn at the same staff-position and if it finds one 
    makes NoteHead, Stem, Flag, Dots (and more?) transparent.
    
    I'd be interested in further results!

I suspect that you may want to make DotColumn, rather than Dots, transparent.

HTH,
