horicontally shift of polyrhythmic staves

[Jonathan Scholbach]

Hi,

I would like to set the following scenario:

In a polyrhythmic piece with multiple staves one staff starts a quarter note later than the others. I need to horizontally shift this stave for the "duration" of a quarter note. How can I do that?

To illustrate what I want I post the following ME, which shows a (dissatifactory) workaround, where the rhythmical structure is represented correctly. However this is dissatisfatroy, because I do not to want  cheat with \set Timing.measureLength. And I want the bracket of the later starting staff (the third one in my ME) to be shifted to the right, because I think it represents the composer's musical idea better.

Thank you,

Jonathan
