WieWaldi I haven’t read every post but scanned through this . Personally, I find the original notation with the ledger lines in the treble clef to be the most straightforward. But if you want an alternative, rather than doing the octave down, I’d just change the clef marking in the upper staff where needed, to the bass clef. In this example, I’d just do it for the final chord. I think this is less confusing than thinking about transposing the chords down an octave, which is an additional mental step. Here’s an example with lots of clef changes:
And another where both upper and lower staves indicate the same clef:
Addendum: I’m not opposed to ‘re-writing’ something to make it easier to mentally parse, but the more I think about the example in the original post, the more I think the original notation is the easiest to parse, and the alternatives add issues that probably create more issues than they solve.
