Yes, this condenses the function quite a bit.

Thinking about the problem some more, I came up with a way to find the
grobs to either side of the note column without creating and manipulating
alists.  I take the filtered list of grobs you created with "read-out,"
then sort it directly by X-coordinate in ascending order; the bounding
grobs are then adjacent in the list.

I get the same results with your examples.  I didn't work out all the
conditions so I'm sure it's easily breakable :)
